When planning any landscaping project in Toronto, it's essential to be aware of the local bylaws that could affect your design. From tree removal to fence height restrictions, Toronto’s regulations can impact everything from planting trees to building decks. Failing to comply can result in delays, fines, or even forced changes. Here’s a guide to the most important landscaping bylaws in Toronto and how you can ensure your project stays compliant.
1. Tree Removal Bylaws
In Toronto, mature trees are protected by the city’s tree protection bylaw. Removing or injuring a tree on private property often requires a permit if the tree’s diameter is above a certain size.
Bylaw Overview: Any tree on private property with a diameter of 30 cm or more (measured 1.4 metres above the ground) is protected under the Private Tree Bylaw. You must apply for a permit to remove or severely prune these trees. For more information on tree removal, visit the City of Toronto's Tree Removal Bylaw page.
Homeowner Tip: Always check the tree bylaw before removing any large trees. You may need to submit an arborist report with your application, and replanting may be required.
2. Fence Bylaws
Fences are a common feature in landscaping, but Toronto has strict regulations on their height and placement, particularly near property lines.
Bylaw Overview: In Toronto, the height limit for fences in front yards is 1.2 metres, while rear and side yard fences can reach up to 2 metres. Check out the full Fence Bylaw details here.
Homeowner Tip: Ensure that your fence complies with height regulations, especially if it borders a neighboring property. Disputes can arise if fences don’t meet city standards.
3. Decking Regulations
Building a deck is a great way to enjoy outdoor space, but Toronto has bylaws in place that dictate where and how you can build one.
Bylaw Overview: Decks that are more than 0.6 metres (24 inches) above the ground require a permit. Additionally, there are setback requirements from property lines. You can find more details about deck permits on the City of Toronto Building website.
Homeowner Tip: Always apply for a permit before building your deck. Make sure the design complies with the city’s regulations on size, placement, and materials.
4. Accessory Structures Bylaws
If you’re thinking about adding a shed, pergola, or other outdoor structure, Toronto has specific rules regarding accessory structures.
Bylaw Overview: Structures under 10 square metres (107 square feet) generally don’t require a permit, but there are still regulations regarding placement and use. Larger structures will need a permit, especially if they are too close to property lines or if they have utilities. For further information, visit the Accessory Structure Guidelines page.
Homeowner Tip: Even for smaller projects, be sure to check the bylaws regarding distance from property lines and height restrictions.
5. Drainage and Grading Regulations
When modifying the grading of your property for landscaping purposes, it's important to ensure you’re not disrupting natural drainage patterns. Toronto has strict rules on this.
Bylaw Overview: You cannot alter your land in a way that causes water to drain onto a neighbor’s property. The city's Drainage Bylaw provides details on the proper way to handle water runoff and avoid liability.
Homeowner Tip: Make sure any landscaping or regrading you do respects drainage bylaws. Poor planning can lead to disputes with neighbors or even fines.
6. Pool and Hot Tub Installation

Pools and hot tubs in Toronto require compliance with strict safety regulations, particularly regarding fencing and barriers.
Bylaw Overview: A pool or hot tub must be enclosed by a fence that is at least 1.2 metres high with self-closing gates. A permit is required before construction begins. Learn more about pool bylaws and permit requirements here.
Homeowner Tip: If you’re considering installing a pool or hot tub, be sure to apply for a permit and plan for the necessary safety enclosures.
