Toronto issues more building permits than any other city in Canada. The city issued 33,967 permits in 2025, representing about $7.2 billion in declared construction value. For contractors, subcontractors, and material suppliers operating in the GTA, that data is the most complete map of construction activity available anywhere.
What Toronto’s permit data includes
Each Toronto building permit record contains:
- Address, exact project location, including unit number for condo work
- Type of work, New Construction, Addition, Alteration, Demolition, Conditional Permit, Change of Use
- Declared value, owner-declared construction value
- Contractor name, the primary permit holder on file
- Issue date, when the permit was formally issued
- Description of work, free-text field describing scope
- Ward, which of Toronto’s 25 wards the project sits in
Toronto’s open data portal publishes this dataset, typically updating daily on business days.
The scale of Toronto’s market
Permit volume has been broadly stable over recent years: 33,550 in 2022, 33,559 in 2023, 32,624 in 2024, and 33,967 in 2025. Through early July 2026 the city had already recorded 16,960 permits, suggesting a similar annual pace. Numbers as of the July 2026 warehouse snapshot.
With roughly 33,000 to 34,000 permits issued each year, manual monitoring is not practical. A contractor checking the city’s open data portal every morning would spend hours sorting, filtering, and comparing files, only to miss the permits that fell through gaps in their filter logic.
The more useful question is not “how do I find all the permits” but “how do I find the permits that match my work type, project size, and geography, before competitors do.”
How long approvals take
Toronto is one of a small number of Canadian cities that publishes elapsed processing time with each permit record. Across the past 24 months of issued permits, the median approval time is 32 days and the average is 82 days. The spread matters: most permits clear in about a month, but complex new-construction applications skew the average well above that. For new construction bids, expect the application phase to run considerably longer than the median.
What contractors use it for
Identifying imminent projects. An issued building permit typically means construction starts within 30 to 90 days. Specialty trades, HVAC, electrical, plumbing, concrete, use permit issuance as the trigger to reach the GC before they’ve finalized their sub list.
Tracking competitor permit volume. Toronto’s permit data includes the named contractor for each permit. If a competing GC pulled 40 permits in North York last quarter, you know exactly where their capacity is going. This intelligence shapes how you price bids and which clients to pursue.
Finding repeat developers. Developers who pull multiple permits in the same neighbourhood over multiple years are among the most valuable relationships in any contractor’s book. Permit history identifies them systematically, before anyone else has noticed the pattern.
Market segment analysis. The mix of new construction versus alteration permits shifts with the economic cycle. When new condo starts slow, alteration volume often rises as owners renovate rather than buy. Watching permit type composition over time gives you a lead indicator on where volume will land before you feel it in your pipeline.
Toronto’s geography: where the volume is
Toronto’s permit volume is not evenly distributed. The downtown core, North York City Centre, and Scarborough Town Centre account for a disproportionate share of high-value new construction. Mid-rise residential is concentrated along major avenues. Industrial and commercial alterations cluster in Etobicoke and Scarborough.
Filtering by ward or neighbourhood is often more useful than filtering by project value alone, a $200,000 commercial alteration in Leslieville is a different opportunity than the same value job in the Entertainment District.
The pre-permit window
Toronto publishes two separate datasets that most contractors ignore. In addition to issued permits, the city tracks Committee of Adjustment applications and Site Plan Approval submissions, both of which represent projects months before a building permit is filed.
When a developer submits a site plan application, they are planning a project, but no permits have been pulled, no GC has been hired, and no sub list exists. This is the moment to build the relationship.
SiteWire’s Pre-Permit feed monitors both issued permits and active applications in review for Toronto, giving subscribers a head start of typically 60 to 90 days over competitors who only watch issued permits.
Setting up a practical filter
The most effective Toronto permit alert is narrower than most contractors expect. A structural framing crew does not need alerts for $50,000 renovation permits. A window supplier does not need alerts for interior alteration work.
Useful filter combinations for Toronto:
- New construction, $2M+, major residential and commercial builds, primary GC target
- Addition, $500K+, significant expansions, often less competitive than new builds
- Alteration, $1M+, large-scale commercial renovations, repeat client opportunities
- Specific wards, focus on the geography where you have existing relationships
