Compare 439 contractors across Ontario by rating and review history - then read what Ontario actually requires of them before you pick up the phone.
Where we cover
Grouped by region, because contractors work across municipal boundaries. A roofer in Oakville serves Burlington, so searching one town alone would hide them.
Written by us, not scraped
Ontario restricts who may do plumbing, electrical and refrigeration work. Most other trades are unregulated. Each guide explains which rules apply, what the work costs, and what to ask.
Yes. Plumber (306A) is a compulsory trade in Ontario - working without certification is illegal, not just inadvisable.
Yes, twice over. The person needs a 309A Certificate of Qualification; the business needs an ECRA/ESA Electrical Contractor Licence.
Yes for the parts that matter. Gas work requires TSSA certification, and refrigerant work requires a 313A or 313D certificate plus environmental handling certification.
No. Roofing is not a compulsory trade in Ontario, so there is no licence to verify - which makes insurance and WSIB coverage the checks that matter.
No provincial licence is required. Installation quality is governed by manufacturer specification and the Ontario Building Code rather than by a trade certificate.
No. Renovation contractors are not licensed in Ontario - but the sub-trades they hire may be, and the permits are the real accountability mechanism.
A running toilet is twenty dollars of parts and half an hour. Hiring that out costs $150. We will tell you which jobs are worth doing yourself, and exactly where to stop - nothing touching gas, the panel, or a roof.

Directories usually make money by selling position. This one does not, which is the only reason the ranking means anything.
A contractor cannot pay to rank higher, be featured, or have a negative review hidden. Ordering comes from a published formula, and that is the whole product.
We do not verify licences or insurance, and we say so on every profile. Our guides show you how to check them yourself, because that check genuinely matters.
No lead selling, no forms that route your project to five companies. When you contact a contractor here, you do it directly through their own number.
Across every area
Star rating weighted for review volume, so a 5.0 from three people does not outrank a 4.7 from four hundred.
