In Ontario, "landscape architect" is a protected title: only Full Members of the Ontario Association of Landscape Architects can use it, after accredited education, supervised experience and the LARE exam. A landscape designer is not regulated by law, and the main voluntary credential is Landscape Ontario's Certified Landscape Designer (CLD). Most residential and cottage projects suit a designer or design-build firm, while public, large or site-plan projects need a landscape architect.
Key takeaways
The difference comes down to licensing and scope. In Ontario, "landscape architect" is a protected title: only Full Members of the Ontario Association of Landscape Architects (OALA) may use it, and getting there takes accredited education, supervised experience and the Landscape Architect Registration Examination (LARE). A landscape designer is not regulated by law. Training ranges from college horticulture programs to years in the field, and the main voluntary credential here is Landscape Ontario's Certified Landscape Designer (CLD). For most residential yards, cottage lots and small commercial sites, a designer or a landscape design and build firm is the right fit. For public spaces, large developments and projects that need a stamped landscape plan for municipal approval, you need a landscape architect.
At Forty Five Scapes we get this question often, usually from homeowners in Midland and Penetanguishene who are not sure whether their project is big enough to need an architect. Both professions plan outdoor spaces people use every day. They differ in training, legal responsibility, the size of project they usually take on, and how they work with engineers and contractors.
This guide is written for homeowners, cottage owners, commercial property managers and anyone weighing a career in the field. It covers the history of both roles, education and licensing in Ontario, typical project scope, cost and how each one fits with a design-build contractor.

Historical Roots: Cultivating Our Outdoor Spaces
For thousands of years, societies have integrated natural beauty and functional utility into their surroundings. From the legendary Hanging Gardens of Babylon to the walled pool gardens of ancient Egypt, people have long built green space into their towns and estates.
Renaissance Italy and then 17th-century France brought formal gardens, such as those at the Palace of Versailles, with strict geometry and elaborate water features. Over time, we saw two distinct paths emerge:
- Large-Scale Public Planning:
Visionaries like Frederick Law Olmsted (often called the father of modern landscape architecture) introduced disciplined planning for city parks and communal spaces, laying the groundwork for today's licensed landscape architects. - Smaller-Scale or Private Projects:
Local gardeners and horticulturalists honed their skills on residential gardens or small community plots, which evolved into the profession we now know as landscape design.
Today the two roles work independently but often collaborate on projects that combine structural complexity with artistry. At Forty Five Scapes we work with both, and each has a part in getting good outdoor living areas built.
Education and Licensure: A Key Distinction
The clearest difference between landscape designers and landscape architects is formal education and licensing:
- Landscape Architects:
- Typically complete an accredited bachelor's or master's degree in landscape architecture.
- Must accrue real-world experience under a licensed professional.
- Pass the Landscape Architect Registration Examination (LARE), which is required for licensure in Ontario as well as in U.S. states that regulate the profession.
- This ensures proficiency in technical areas such as grading, drainage, environmental regulations, and construction documentation.
- Landscape Designers:
- Generally not required to hold a license, so educational backgrounds can vary widely.
- May have credentials in horticulture, fine arts, design, or might be self-taught but well-practiced.
- They often focus more on aesthetic and plant-related expertise rather than advanced engineering or structural considerations.
If you're planning a large-scale development, a public park, or a complex commercial project, you'll likely need a landscape architect for their technical and regulatory know-how. On the other hand, if you're a homeowner wanting to refresh your backyard garden, a landscape designer is often the better fit. Either way, Forty Five Scapes works with both.
How the two roles are regulated in Ontario
The OALA Act, in force since 1984, controls who can call themselves a landscape architect. Only OALA Full Members can use the title, interns must use wording such as "Landscape Architectural Intern," and a firm can only put "landscape architects" in its name if a Full Member directly supervises its landscape architecture work. Using the title without membership is an offence. You can check anyone's status in the OALA's public "Find a Landscape Architect" directory.
Nothing in Ontario law restricts the title "landscape designer." The closest thing to a standard is Landscape Ontario's Certified Landscape Designer (CLD) program, which asks for seven years of experience (or a mix of schooling and field work), a portfolio review by a panel of industry judges, a written exam on horticulture, plant identification, grading, construction details and professional practice, and ongoing continuing education. When you interview a designer, ask about training, certification and, above all, built work you can go and look at.
Scope of Work: Cozy Retreats vs. Grand Public Spaces
A simple way to see where landscape designers and landscape architects differ is by looking at project scope:
- Landscape Designers
- Frequently handle residential or small-scale commercial spaces.
- Specialize in plant selection, artistic layouts, and on-the-ground solutions.
- Shine in spaces like seasonal flowerbeds, intimate seating zones, or small water features.
- Landscape Architects
- Address more complex, large-scale projects.
- Oversee site engineering, including stormwater management, structural concerns, and municipal approvals.
- Excel in creating corporate campuses, city parks, or ecological restoration projects.
That said, an architect might still design a private backyard—especially if it has challenging terrain or strict regulatory requirements—while a designer could handle certain aspects of a bigger commercial plot, focusing on aesthetics or plant palettes. At Forty Five Scapes we match the expertise to the job, whatever its size.
Where a design-build firm fits
Many homeowners end up with a third option: a design-build landscaping company that produces the design and then builds it under one contract. The designer works next to the crew that will dig, grade and lay stone, so the plan is priced and checked for buildability before you commit. When a part of the job needs an engineer's or a landscape architect's stamp, such as a tall retaining wall or a site plan for a commercial lot, a good design-build firm brings that professional in rather than skipping the step.
Balancing Art and Science: Different Design Philosophies
Though both roles design outdoor spaces, each profession brings a slightly different emphasis:
- Landscape Designers
- Often prioritize beauty, horticulture, and the user's emotional experience.
- Might ask: "Which colours and textures feel most inviting? How can we make this space child-friendly or pet-friendly?"
- Excel at designing spaces that reflect personal styles—like cottage gardens, minimalist modern yards, or tropical-inspired retreats.
- Landscape Architects
- Blend artistic vision with technical and regulatory requirements.
- Conduct site analyses, assess local climate, and ensure designs meet all building codes.
- Might ask: "How do we preserve existing ecosystems, handle drainage effectively, and align with local zoning?"
There is plenty of overlap. Some architects have a strong eye for planting and detail, and many designers know structural layout well. In our experience, the best results come when both kinds of thinking are applied to the same site, so the space works well and looks good.
Construction and Technical Expertise
When it comes to advanced structural or engineering issues, landscape architects are usually the experts:
- Grading and Drainage: Making sure water flows away from buildings and walkways.
- Structural Elements: Integrating materials like concrete, steel, or stone for retaining walls, walkways, or terraces.
- Permitting and Zoning: Navigating local codes and regulations.
- Site Engineering: Planning roads, footpaths, or multi-level landscaping.
Grading is a good example of where the technical side shows up on even a small residential job. The Town of Midland's lot grading checklist asks for grass and other soft areas to slope at least 2% away from buildings and hard surfaces at least 1%. Whoever draws your plan, the first site visit should start with three numbers: the area in square metres, the fall across the yard and the volume of material the design will need.

- Split odd shapes. Break the yard into rectangles, triangles and circle segments, measure each, then add them.
- Level a string line. Stretch it between two stakes and set a line level in the middle so the string is dead level.
- Measure down at each stake. The difference is the rise. Divide by the run between stakes and multiply by 100 for percent.
- Volume = area × depth. Convert depth to metres first. Tell the supplier the compacted depth you need.
- Check against the standard. In Midland, grass must fall at least 2% away from buildings and hard surfaces at least 1%.
Landscape designers often have a solid grasp of simpler construction techniques and know when to bring in structural or engineering pros for more complex tasks. If you are planning a two-tiered backyard with retaining walls or a boulder waterfall, get an engineer or landscape architect involved early. Under the Ontario Building Code, a retaining wall more than 1 m high next to public property, a building entrance or private property open to the public needs a building permit and an engineered design (our guide to retaining wall permits in Ontario explains when that applies). Forty Five Scapes handles the design and construction side and coordinates the engineering where a project needs it.
Caring for the Environment: Sustainability at Every Scale
At Forty Five Scapes we try to leave a light footprint on every site. Both designers and architects play key roles in sustainability, but at different scales:
- Landscape Architects
- Look at the big picture—often analyzing entire watersheds or ecosystems.
- Design for stormwater management, natural habitat preservation, and long-term environmental health.
- Consider large-scale factors like soil erosion, carbon footprints, and the overall resilience of a landscape to climate changes.
- Landscape Designers
- Handle micro-level sustainability—choosing native plants, using compost, or encouraging pollinator-friendly ecosystems.
- Might focus on organic approaches to pest control, minimal irrigation systems, or eco-friendly hardscaping materials.
At any scale, both roles can shape a property so it works with the natural site and uses less water, fertilizer and fuel to keep up.
Working with Clients: Residential vs. Commercial Projects
At Forty Five Scapes, most of our work is for homeowners and cottage owners, but we also take on commercial projects. Generally:
- Landscape Designers
- Often interact with homeowners or small-business owners.
- Provide more personal, hands-on guidance, which suits home gardens and community spaces.
- Conversations tend to cover colour palettes, seating arrangements, or decorative lighting.
- Landscape Architects
- May collaborate with city councils, real estate developers, or corporate boards on bigger budgets.
- Present detailed site plans and oversee compliance with zoning laws or environmental regulations.
You will see overlap. Some designers do well in corporate settings, and some architects enjoy crafting small but intricate residential spaces. The key is matching the professional's skill set and experience to the scale and demands of your project.
Teaming Up: Collaboration Across Disciplines
Most modern landscaping projects bring together multiple experts:
- Architects/Builders: Fitting building structures to the outdoor spaces around them.
- Civil Engineers/Surveyors: Handling terrain analysis and major infrastructure challenges.
- Ecologists: Preserving wildlife corridors and maintaining biodiversity.
- Municipal Planners: Ensuring the project meets community needs and zoning regulations.
Landscape architects often helm large-scale projects, orchestrating these specialists. Landscape designers, meanwhile, might zero in on plant palettes, decorative elements, or user-flow. At Forty Five Scapes we spend a lot of our time coordinating these people so the pieces of a project fit together.
Design Technology: CAD, 3D Renderings, and More
Today's landscaping professionals use an array of digital tools:
- CAD (Computer-Aided Design): For accurate drafting and dimensioning.
- 3D Rendering Software: Creating realistic previews of how your landscape evolves.
- GIS (Geographic Information Systems): Analyzing terrain and ecosystem data at large scales.
- Drones: Aerial surveys for mapping and project visualization.
- AR/VR Experiences: Letting clients virtually "walk through" their future space.
While landscape architects often adopt more advanced mapping and modeling software (like GIS), landscape designers may rely heavily on visually rich 3D rendering tools to showcase aesthetic concepts. At Forty Five Scapes we use 3D landscape design so you can see the plan before anything is dug.
Budgeting and Project Management
Every landscaping project—big or small—needs careful budgeting and project oversight:
- Landscape Designers
- Typically handle simpler budget proposals, often for residential clients.
- Smaller teams and fewer regulatory hoops.
- Billing can be hourly, project-based, or a mix of both.
- Landscape Architects
- Submit more formal, detailed proposals and full sets of construction drawings and specifications.
- Oversee larger budgets, multiple subcontractors, and phased timelines.
- Must adhere to public bidding rules if working with municipal or governmental clients.
In either case, ask how the professional will report progress and handle changes. At Forty Five Scapes we give regular updates and agree on a process for changes before work starts. Good project management matters as much on a small patio as on a park.
Charting Your Own Path: Careers in Landscape
Wondering which path might suit you best?
Landscape Designer Route
- Education: Ranges from short certificate programs to self-guided learning.
- Portfolio Emphasis: Before-and-after photos showcasing plant expertise and creative flair.
- Work Environments: Residential firms, local nurseries, garden centres, or freelance design services.
Landscape Architect Route
- Education: Must be from an accredited bachelor's or master's program in landscape architecture.
- Licensure: Years of supervised experience plus the LARE exams to earn the protected title "Landscape Architect," granted in Ontario by the OALA.
- Work Environments: Public planning agencies, large design or architecture firms, major infrastructure projects, or private consultation on large-scale developments.
Many professionals start as designers, then pursue additional schooling to become architects. Others stay on one track for their whole career. The choice depends on your interests, lifestyle, and long-term aspirations.
Real-World Examples of Collaboration
- Downtown Pocket Park (Architect-Led)
A city wants to turn an underused lot into a green space with a small amphitheatre. A landscape architect manages regulations, drainage, and structural details. A landscape designer refines the planting schemes and seating areas so the space feels comfortable. - Residential Courtyard (Designer-Led)
A homeowner envisions a koi pond and lush greenery in a small courtyard. A landscape designer focuses on plant selection and seating. An engineer is brought in for the pond's construction specifics. - Corporate Campus Green Roof (Architect-Led)
A tech firm aims to install a sprawling green roof. A landscape architect oversees load-bearing issues and advanced drainage systems. A landscape designer assists with aesthetic touches like seasonal blooms and seating arrangements for employee relaxation. - Community Garden Makeover (Designer-Led)
A local nonprofit seeks a more inviting space for gardening classes and children's programs. A landscape designer updates the layout, adding raised beds and pollinator flowers. The result is a hands-on teaching space in the middle of the neighbourhood.
Planning a 2027 landscape design project: designer or architect?
If you want to build in 2027, use the winter to settle who you need. Write down what the project includes and check it against the triggers in this guide. A backyard patio, plantings and lighting are designer or design-build work. A commercial site plan, a public space or a wall over 1 m beside a sidewalk or entrance brings in a landscape architect or engineer.
Design work fits best between November and February. That leaves March and April for permits, approvals and material orders before the ground thaws, which in Simcoe County is usually late April or May. Crews book their spring calendars early, so a signed design by late winter puts you near the front of the line. If a stamped landscape plan is part of a municipal site plan application, start earlier still. Those reviews can take months, and the landscape plan is only one piece.
- Confirm credentials. Check the OALA directory for architects and ask designers about CLD certification and recent local work.
- Ask about permits up front. Retaining walls, decks and grading changes can each need approval.
- Plan for water. Native plantings, permeable paving and well-graded swales cut maintenance and handle spring runoff.
- Bring measurements. Area, slope and photos of the site speed up the first design meeting.
Frequently Asked Questions
- Who should I hire for a small backyard remodel?
For simpler projects, like adding flowerbeds or a fire pit, a landscape designer is usually the right choice. If you need major grading or structural elements, consult a landscape architect. - How do I know if my project requires a licensed landscape architect?
This depends on local regulations and the complexity of your plans. Most Ontario homeowners do not need one for a backyard project. Municipalities often ask for a landscape plan prepared by a landscape architect as part of a site plan application for commercial or multi-unit development, and structural items such as tall retaining walls need an engineer's design. - Can a landscape designer become a landscape architect?
Yes. Many designers go back to school for a degree in landscape architecture and then complete their licensure requirements. - Is there a cost difference between designers and architects?
Landscape architects typically charge more due to higher education and licensing. However, seasoned landscape designers with in-demand skills can also command premium rates. - Do both handle ongoing maintenance?
Not usually. While some design firms may offer maintenance, many focus only on planning and installation. Forty Five Scapes can recommend reliable local services or schedule maintenance add-ons. - Are they both eco-friendly?
Both can be. Designers tend to use micro-scale sustainability (native plants, organic soil amendments), while architects often handle larger-scale environmental solutions (wetland restoration, stormwater management). - Is "landscape architect" a protected title in Ontario?
Yes. Under the OALA Act, only Full Members of the Ontario Association of Landscape Architects can use the title. "Landscape designer" is not a regulated title. - What does CLD mean after a designer's name?
It stands for Certified Landscape Designer, a Landscape Ontario credential that requires years of experience, a juried portfolio review, a written exam and continuing education.
Choosing the right professional for your project
The split between a landscape designer and a landscape architect comes from training, legal responsibility and scope, but both aim to build outdoor places people want to use. Match the professional to the job: a licensed landscape architect for regulated, large or public work, and a designer or design-build team for most homes and cottages.
For Ontario credentials, the Ontario Association of Landscape Architects lists licensed members, and Landscape Ontario lists Certified Landscape Designers. Our longer guide, Landscape Designer vs. Landscape Architect in Ontario: Which Do You Actually Need?, walks through specific project types.
If you are planning a project in Midland, Penetanguishene, Georgian Bay or Muskoka and want a straight answer on what it needs, get in touch with Forty Five Scapes. We will tell you whether a design-build plan covers it or when to bring in an architect or engineer.
