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

No permit is needed for an ordinary fence in Toronto, but it must be built to the by-law. Chapter 447 caps a front-yard fence at 1.2 metres within 2.4 m of a street lot line and an ordinary back-yard fence at 2.0 metres. A pool is the exception: it needs a Pool Fence Enclosure Permit, a four-sided enclosure with a self-closing, self-latching gate, and an inspection before any water goes in. Breaking any of it carries a fine of up to $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" at any point along its length, not 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 carve-out, so a rear fence along a lane does reach 2.5 metres.

2.5 metres is not the general back-yard number. Row 6 needs the fence to abut multi-residential or non-residential land, a public highway or a walkway and not to be a row 3, 4 or 5 fence, so a driveway-side or deck fence falls 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 exceed 2.5 metres and 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 adjacent 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 spans the whole width, the flanking-street strip beside your house is front yard, and row 1 caps a fence within 2.4 m of any street lot line, flanking included, at 1.2 metres. 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. Flankage exemptions are also granted least often: 67 per cent against 82 per cent for rear and side yards.

Sightlines override 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, and § 447-1.2D bans vegetation or objects that defeat it.

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 must first get a Zoning Applicable Law Certificate from Toronto Building, then 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" (its $198.59 is the superseded zoning fee), and 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 usable for swimming, wading or bathing "in which the water depth at any point can exceed 600 millimetres": most inflatable and above-ground pools included. A hot tub or spa is exempt only with a substantial cover permanently attached to it or its supporting structure, locked whenever not in use. An above-ground pool erected before July 6, 2000 escapes the rules only if it meets all six of § 447-1.3F(1)'s standards, which are joined by "and": the pool is not less than 1.2 metres above grade; a guard not less than one metre high runs around any platform or deck; 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 is closer than 1.2 metres to a lot line; and the access point is protected by a gated enclosure meeting Subsections B through E. The two most often forgotten are the deck guard and the no-climbing rule: a ladder, pump or deck rail left against the outside defeats the exemption and leaves the pool unguarded.

The enclosure must enclose the pool area completely, with no opening except a compliant gate. The rule that decides most back yards is § 447-1.3C(1): it "shall be designed and constructed so that all entrances to any building are located outside the enclosed area". Fencing the pool and leaving the back door inside is offside. C(3) adds that a building wall forming part of the enclosure may give no access through it (by C(4), on enclosures permitted more than 30 days after November 20, 2007 and on older fences substantially demolished or beyond repair). Anything lawful before June 20, 2018 is deemed to comply until replaced. Minimum height, 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, 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 be kept locked at all times except when the enclosed area is in use. A double gate needs one leaf to that standard plus a second with a lockable drop bolt reaching at least 25 millimetres into concrete, asphalt or paving stones, kept locked bolt-down. Powered closers need an outage 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 (a tree, a woodpile, an air conditioner) unless 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 permitted ground gap is under a gate: where a hard surface runs 500 millimetres each side of the gate, clearance under it may be no more than 100 millimetres.
• "Non-climbable" means a 1.2-metre vertical face: chain-link mesh no greater than 38 millimetres square for 1.2 metres vertically; otherwise no horizontal opening or step wider than 38 millimetres over that height, or, where horizontal components are at least 1.2 metres apart, no opening greater than 100 millimetres. The same split governs 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 that does not block the view of the pool from a door or window on the main living area.

Sharing a fence with a neighbour

Ontario arbitrates boundary fences: under the Line Fences Act an owner asks the municipality to appoint fence-viewers, three of whom must attend the viewing, to split the cost and settle the design, with 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: 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, and for a 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: $200.00, non-refundable. Neighbours are notified (everyone within a 60 metre radius for a front-yard fence), and you post notice on the property 10 days before the meeting.

Enforcement runs on complaints to 311. Section 447-1.4 provides a fine of not more than $100,000 on conviction, a special fine equal to the fair market value of any economic advantage gained, the same exposure for a corporate director who concurs, and, every offence being continuing, up to $10,000 a day, the total permitted to exceed $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.
