Five things to confirm with any firm, on this list or not, before you sign. The rules below are Ontario's and London's.
Ask the firm for a clearance certificate from the WSIB, which confirms it is registered for workers' compensation and its account is in good standing. The certificate confirms the firm is registered with the WSIB and up to date on its premiums, so check its dates cover your job.
Ask for a certificate of insurance that names the firm and shows commercial general liability coverage in force for the dates of your job, and check that the subcontractors it brings in are covered too.
Building permits for homes in London come from the City of London, and moving fixtures or drains, adding a bathroom or changing circuits usually needs one. Agree in writing who applies for the permit and books the inspections.
Get the scope of work, the payment schedule tied to stages of the work, start and finish dates, how changes are agreed and priced, and who handles permits and cleanup, all in one signed contract before any work starts.
A renovation is not a new home, so the new home warranty rules usually do not apply: get the firm's own workmanship warranty in writing, with what it covers and for how long. Renovators in RenoMark, the Canadian Home Builders' Association program, offer a minimum two-year warranty on their work.
The 10 firms on this list fall into 4 groups, read from what each firm's own site says it does and how it is listed on Google.
Renovation companies renovate existing homes, one room at a time or all of it at once.
Bathroom specialists work mainly on bathrooms and ensuites, including the waterproofing behind the tile.
General contractors run building projects of many kinds and bring in the trades each job needs.
Design-build firms design the project and build it under one contract, so one firm answers for the drawings and the work.
Water. A shower that is not properly waterproofed behind the tile can leak into the walls for years before anyone notices. Ask which waterproofing system the firm uses and how it handles the shower floor and the joints.
A like-for-like update usually does not. Moving the toilet, shower or drains, adding a bathroom, or changing electrical circuits generally does. Your municipality decides, so confirm before work starts.
Usually. The firm removes the tub, reworks the drain for a shower, waterproofs the walls and floor, and builds or sets the shower base. Ask how it will handle the drain position and the waterproofing at the shower entry, especially for a curbless shower.
A renovation strips the room back to the studs and rebuilds it, which is the chance to fix hidden water damage, move fixtures and redo the waterproofing. A refit replaces fixtures and finishes in place. A refit is quicker, but it cannot fix problems behind the walls.
Ask the firm for a clearance certificate from the WSIB. The certificate confirms the firm is registered with the WSIB and up to date on its premiums, so check its dates cover your job.
Building permits for homes in London come from the City of London. For bathroom renovation, moving fixtures or drains, adding a bathroom or changing circuits usually needs one. Many firms apply for the permit as part of the job, so agree who does it before you sign.
Bathroom renovation prices by scope for Ontario and Calgary in 2026, fixture and tile prices, what moving a toilet or shower adds, and the tax and permit lines.
The order of a bathroom renovation with the days each step takes, the waterproofing and cure times that set the pace, permits and inspections by city, and the lead times for glass and fixtures.
The features that make a bathroom safe to use with age or a disability, the clearances designers work to, what it costs in 2026, and the federal and BC tax credits.
