Toronto adds a city layer on top of everything Ontario already requires. The big one is the Building Renovator Licence, a municipal licence unique to Toronto that most other Ontario cities do not have. On top of that sit Toronto's own permit process, a strict construction noise by-law, heritage rules, and the highest development charges in Canada. This guide assumes you already know the Ontario baseline and focuses on what the City of Toronto adds.
The Ontario baseline, briefly
Ontario is a 13% HST province. The minimum wage is $17.60 an hour, rising to $17.95 on 1 October 2026. WSIB is the workers comp board (average around $1.23 per $100, construction classes higher). The builders lien is preserved within 60 days and perfected by 90, with a 10% holdback, and prompt payment plus mandatory adjudication are in force. Ontario small claims now reach $50,000 (raised from $35,000 on 1 October 2025). Ontario has 23 compulsory trades, and the 2024 Ontario Building Code has been in force since 1 January 2025. All of that applies in Toronto. What follows is the extra city layer.
The Building Renovator Licence
Any business that repairs or renovates buildings, or simply advertises renovation services, inside City of Toronto limits must hold a Building Renovator Licence under Toronto Municipal Code Chapter 545. It sits on top of the provincial layer and is the exception in Ontario: Vaughan, Pickering and most other municipalities do not require an equivalent.
You apply with your provincial business registration, an Operating Information Questionnaire, a Health and Safety Declaration and photo ID, and you sit a one-time trade examination. Fees change every year, so confirm the current application, licence, examination and annual renewal amounts on the City of Toronto licensing page before you apply rather than relying on a figure quoted elsewhere.
There is no separate Toronto licence for plumbers, electricians or gas fitters: those stay regulated provincially by Skilled Trades Ontario, the Electrical Safety Authority and the TSSA. But plumbing and drain contractors do hold their own city categories.
The building permit process
Toronto charges a permit fee on a Service Index times floor-area formula, with a published minimum fee that is updated annually. As of 16 February 2026, all permit applications must go through the City's digital portal on the updated form; paper is no longer accepted.
Real-world timelines for a clean residential submission run roughly 6 to 12 weeks. Interior and basement renovations are quicker, home additions and custom builds slower, and the big delays come from Committee of Adjustment variances (2 to 6 months) and heritage approvals (3 to 12 months). Laneway and garden suites carry their own floor-area permit formula.
Development charges: the highest in Canada
Toronto's development charges are the highest in the country, running into six figures for a single-detached home. They are also volatile: a federal-Ontario partnership announced in 2026 may temporarily cut Ontario DC rates by up to half for municipalities that opt in. Because the rate moves and the cuts roll out unevenly, never quote a client a fixed development charge from memory. Pull the current figure from the City of Toronto development charges page and the relevant by-law at the time you apply, and treat permit and addressing fees the same way. This guide does not state a fixed DC figure on purpose.
City-specific rules that catch trades out
- Noise by-law (Chapter 591). Construction noise is allowed Monday to Friday 7 a.m. to 7 p.m. and Saturday 9 a.m. to 7 p.m. only. Sundays and statutory holidays are prohibited entirely. Overnight concrete pours or crane work need a formal Noise Exemption Permit, with a mitigation plan and seven days' public posting. This catches out trades used to weekend work.
- Heritage. Properties designated under Part IV or Part V of the Ontario Heritage Act need a Heritage Permit before a building permit issues, and that review can run 3 to 12 months. Part IV demolitions need 60 days' notice to the City.
- Digital-only intake. Since February 2026 there is no paper counter for permits; everything is online.
Common mistakes
- Working in Toronto without the Building Renovator Licence. It is a real, enforceable municipal requirement that most other Ontario cities do not have.
- Quoting a fixed development charge. Toronto's DCs are the highest in Canada and are in flux. Always check the current City schedule.
- Booking Sunday work. The noise by-law bans construction noise on Sundays and statutory holidays outright.
