Frequently asked questions
- How do I find a general contractor in my Ontario city?
- Pick your city from the list below to see general contractors serving that area, along with their phone number and website where available.
- Do general contractors in Ontario need a licence?
- For renovations, there is no province-wide contractor licence in Ontario. New-home builders and vendors, however, must be licensed by the Home Construction Regulatory Authority (HCRA). Regulated trades within a job, such as electrical and gas, still need their own licences.
- Do I need a building permit for a renovation?
- Most structural renovations, additions, and many interior changes require a municipal building permit. Confirm with your city and agree in writing who is responsible for pulling it.
