Ontario companies filed as a general contractor or construction company, with at least one review and recent activity on their profile.
Each company's website was read for kitchens, bathrooms, basements, additions, permits, warranties and other home work.
Firms that do not renovate homes, single trades, design-only studios, referral services and repeat listings were removed.
Owners can correct their own listing, and website links that no longer work are taken off.
The starting point was Google's business data for Ontario companies listed as a general contractor or construction company. Profiles with no reviews, and profiles not updated in the past year, were left out, and repeat listings of one company were merged.
Each remaining company's own website, where one could be read, was checked for the home work it takes on. Companies that build roads, serve only commercial clients, practise a single trade, offer design without construction, or pass leads to other contractors were removed. What is left is a list of firms that say they renovate homes, plus a smaller group whose names point to renovation work.
A company owner can take over a listing to fix its details or add project photos; requests are confirmed by hand before anything changes. The directory is run by Dee Black.
Know who licenses what. Ontario does not issue a provincial licence for renovating an existing home. The Home Construction Regulatory Authority licenses builders and sellers of new homes, so an HCRA number speaks to new-build work rather than renovations. Some cities license renovators themselves; Toronto and Mississauga both do, so in those places ask for the city licence number.
Agree who applies for the permit. Many renovations need a building permit from your municipality, and the rules change from place to place. Mississauga treats finishing a basement as permit work, while Toronto does not ask for one when the finish leaves structure, plumbing and the number of units alone. If your house is a designated heritage property, changes to its listed features also need heritage approval. Put in writing who applies, and keep the inspection records.
Planning a second unit? Since November 2022 the Planning Act has allowed up to three homes on many fully serviced urban lots, such as two in the main house and one in a garden suite. Each unit still needs a building permit and has to meet the Ontario Building Code, so look for a company whose page shows basement work and permit handling.
Electrical and gas are their own trades. Electrical work done for pay needs a contractor licensed through the Electrical Safety Authority, and gas lines and appliances need a TSSA-registered contractor. If a renovation company says it covers both, ask whose licence the work falls under.
Call before anyone digs. Footings for an addition or a deck, fence posts and drainage trenches all break ground. Ontario Dig Authority, formerly Ontario One Call, handles locate requests at no cost and asks for at least five business days of notice.
Plan for asbestos and lead in older houses. Health Canada says homes built before 1990 may hold asbestos in tiles, plaster or insulation, and homes built before 1960 probably have lead paint. It advises testing before work starts and leaving removal to qualified people, so ask how the crew deals with both.
Look up WSIB status. Construction businesses generally have to register with the WSIB, though a firm doing only home renovations, paid directly by the homeowner, may be exempt for itself. You can search a company on the WSIB's site and check its clearance certificate, which lasts up to 90 days.
Read the grid on each company page. It shows what the company's own wording confirms: kitchens, bathrooms, basements, additions, permits, insurance, a warranty and more. A blank means the company has not said either way, which makes it a question for the first call rather than a mark against it. A star rating carries more weight with a long list of reviews behind it.
Not from the province. The Home Construction Regulatory Authority (HCRA) licenses builders and sellers of new homes, not renovators of existing ones. Some cities issue their own renovator licence, Toronto and Mississauga among them, so ask for the city licence number if you live there. Electrical work done for pay needs an ESA-licensed electrical contractor, and gas work a TSSA-registered one.
Many do, and your municipality decides which. Structural changes, additions and new units usually need one; minor finishes often do not, but the lists vary by town. Settle in writing whether you or the contractor will apply.
Since November 2022 the Planning Act allows up to three homes on many fully serviced urban lots, for example two in the house and one in a garden suite. Each unit still needs a building permit and has to meet the Ontario Building Code.
Search the business on the WSIB's online services and ask for its clearance certificate number, which you can verify there. A clearance is valid for up to 90 days. A firm doing only home renovations, paid directly by the homeowner, may be exempt for its own coverage.
Sponsored spots come first and are labelled. After them, companies whose names say renovation work lead, and the rest follow by Google rating weighted by the number of reviews, with firms confirmed to renovate homes placed ahead.
No. The listings bring public details together so you can compare companies; they are not an endorsement. Check licences, insurance and references with the company before you sign.
