Fence and Pool-Fence Rules in Toronto, in Plain English

You need no permit for an ordinary fence in Toronto, but it must meet the by-law. Chapter 447 caps a front-yard fence at 1.2 metres within 2.4 m of a street lot line. An ordinary back-yard fence is capped at 2.0 metres. A pool is the exception. It needs a Pool Fence Enclosure Permit, a fence on all four sides with a gate that closes and latches itself, and an inspection before water goes in. Break any of it and the fine can reach $100,000.

Maximum fence heights, by where the fence sits

Height is measured "from the average grade level measured perpendicular to and one metre away on either side of the fence". Grade means the ground level. It is taken at any point along the fence, not at the low side of a slope. Lattice and toppers count. § 447-1.2B measures the whole barrier, and B(2) treats each described part as its own fence.

*A public lane is not a public highway in rows 1 to 5; "near a driveway" means within 2.4 m of one. Row 6 has no lane exception, so a rear fence along a lane does reach 2.5 metres.

2.5 metres is not the general back-yard number. Row 6 asks two things. The fence has to touch multi-residential or non-residential land, a public highway or a walkway. It also must not be a row 3, 4 or 5 fence, so a driveway-side or deck fence drops back to 2.0 metres. The ordinary fence behind your house is row 9: 2.0 metres. Non-residential land is not 2.5 metres everywhere either: rows 2, 3 and 5 match.

Barbed and chicken wire are not banned outright. § 447-1.2A(2) allows them where the fence may go over 2.5 metres, if the sharp material sits at 2.5 metres or higher on brackets angled 45 degrees inward. Sheet metal and corrugated panels are banned outright. Snow fences are allowed November 15 to April 15. A school fence is capped at 1.5 metres next to a public highway or right-of-way.

Corner lots: the mistake that costs a metre

On a corner lot the front yard is "the space, extended to the full width of the lot, including any side lot line, between the shorter lot line abutting a public highway ... and the nearest wall of the main building." Because it runs the whole width, the strip beside your house along the side street is front yard. Row 1 then caps a fence within 2.4 m of any street lot line at 1.2 metres, side street included. Beyond 2.4 m from both, row 2 gives 2.0 metres. The 2.5-metre row opens only behind the nearest wall of the main building. Build to 2.5 metres in front of that wall and you are a metre over. That side-street frontage is called flankage. Flankage exemptions are granted least often: 67 per cent against 82 per cent for rear and side yards.

Sightlines beat the table. Under § 447-1.2C, any fence within 2.4 m of a driveway must be open-fence construction for at least 2.4 m from the lot line where the driveway begins. Open-fence construction means you can see through it, so a driver sees the sidewalk. § 447-1.2D bans plants or objects that block that view.

When you need a permit, and what it costs

Municipal Licensing and Standards put it plainly in its 2018 review: "the only private fences that require permits are pool enclosures." There is no fence permit in Toronto at any height. So the common claim that a front-yard fence over four feet needs one is false.

A pool takes two steps. Since March 31, 2021 you first get a Zoning Applicable Law Certificate from Toronto Building, a written check that your plan fits the zoning rules. Then you send Municipal Licensing and Standards the form, certificate and site plan for the Pool Fence Enclosure Permit. Reviews take 10 to 20 business days.

Only the zoning certificate is certain. The two Chapter 441 pool-enclosure lines are real published fees. But the City's pool permit FAQ of March 24, 2021 says the pool permit fee "will not be charged until the new amount is determined". The $198.59 it names is the old zoning fee. Nothing published since says which line is billed after the 2021 split. Get the amount in writing before you pay.

Pool enclosures: the rules with no give in them

A "swimming pool" is anything outdoors on private property you can swim, wade or bathe in, "in which the water depth at any point can exceed 600 millimetres". That takes in most inflatable and above-ground pools. A hot tub or spa is exempt only if it has a substantial cover fixed permanently to it or its frame, and locked whenever not in use.

An above-ground pool put up before July 6, 2000 escapes the rules only if it meets all six standards in § 447-1.3F(1). They are joined by "and", so one miss ends it. The pool wall is not less than 1.2 metres above grade. A guard not less than one metre high runs around any platform or deck, a guard being the railing that stops a fall. Pool and guard together are no more than 2.6 metres. The outside of the structure and any guard is free of any element or attachment that may facilitate climbing. No part sits closer than 1.2 metres to a lot line. And the access point is protected by a gated enclosure meeting Subsections B through E. Two get forgotten most: the deck guard and the no-climbing rule. A ladder, pump or deck rail left against the outside kills the exemption and leaves the pool unguarded.

The enclosure has to surround the pool area completely, with no opening but a gate that meets the rules. The line that decides most back yards is § 447-1.3C(1). The enclosure "shall be designed and constructed so that all entrances to any building are located outside the enclosed area". Fence the pool and leave the back door inside, and you are offside. C(3) adds that a building wall used as part of the enclosure may give no access through it. By C(4), that applies to enclosures permitted more than 30 days after November 20, 2007 and to older fences substantially demolished or beyond repair. Anything lawful before June 20, 2018 counts as compliant until it is replaced. Minimum height is measured above the highest outside grade within one metre: 1.2 metres on single residential property, 1.8 metres on multiple residential and non-residential.

Gates

A single gate must sit on substantial hinges. It must be self-closing and equipped with a lockable, self-latching device located on the inside near the top of the gate or on the outside at least 1.5 metres above grade. And it must be kept locked at all times except when the enclosed area is in use. A double gate needs one leaf built to that standard. The other needs a lockable drop bolt, a rod that drops from the gate into the ground, reaching at least 25 millimetres into concrete, asphalt or paving stones. It stays locked down. Powered closers need a power-cut back-up and CSA hardware. Chapter 447 says nothing about which way a gate swings.

Gaps and climbing

• No closer than 1.2 metres horizontally to the water's edge.
• No closer than one metre to any external condition that may facilitate climbing, such as a tree, woodpile or air conditioner. The exception: the enclosure is at least 1.8 metres high for one metre either side of it.
• Nothing attached between 100 millimetres and 1.2 metres above grade on the outside that may help someone climb.
• Non-climbable facing, installed on the outside of the enclosure, must run from no more than 50 millimetres above grade to the required minimum height. The only gap allowed at ground level is under a gate. Where a hard surface runs 500 millimetres each side of the gate, the clearance under it may be no more than 100 millimetres.
• "Non-climbable" means a 1.2-metre vertical face with nothing to grip. Chain-link mesh qualifies at no greater than 38 millimetres square for 1.2 metres vertically. Otherwise no horizontal opening or step over that height may be wider than 38 millimetres. Where horizontal components sit at least 1.2 metres apart, no opening may be greater than 100 millimetres. The same split covers wood boards, metal pickets and glass panels. Horizontal boards are stricter: no more than 20 millimetres apart.
• The side between pool and house must be open construction. It cannot block the view of the pool from a door or window on the main living area.

Sharing a fence with a neighbour

Ontario has a process for boundary fences. Under the Line Fences Act an owner asks the municipality to appoint fence-viewers, local officials who rule on a shared fence. Three must attend the viewing. They split the cost and settle the design, and you get 15 days to appeal ($406.05 in 2026).

None of it is available in Toronto. Article 2 of Chapter 447 reads: "The Line Fences Act, except for section 20, does not apply to all of the City of Toronto." Section 20 is the part a council cannot opt out of. It covers fencing duties on former rail lines beside farmland. The City states the consequence. It does not accept applications for line fence viewing. And "the City does not have a role in resolving disputes about the location or costs of boundary fences between properties."

So agree in writing before anyone digs. Confirm the boundary with an up-to-date survey. If you deadlock, use the City's referral to TNG Community Services for free mediation.

Exemptions, notices and fines

For a fence the table does not allow, apply to Community Council for a site-specific exemption. It costs $200.00, non-refundable. Neighbours are notified, everyone within a 60 metre radius for a front-yard fence. You post notice on the property 10 days before the meeting.

Enforcement runs on complaints to 311. Section 447-1.4 sets a fine of not more than $100,000 on conviction. It adds a special fine equal to the fair market value of any economic advantage gained, and the same exposure for a company director who agrees to it. Every offence counts as continuing, so it also allows up to $10,000 a day, and the total may pass $100,000. In practice, fines have been far smaller. Staff's 2018 review found 73 per cent were $500 or less, in a range of $100 to $5,000, before the ceiling rose from $5,000 to $100,000.
