4. JY Construction | Commercial Renovation Company in Toronto

JY Construction holds a 4.9 rating and backs it with a RenoMark GTA 'Best Commercial Renovation' award in both 2024 and 2026, plus a WSIB leadership award. With only 36 reviews the sample is smaller than others here, but feedback consistently describes an owner and team who solve problems rather than rush through them.

- $10 million commercial liability insurance
- In-house design-build and permit handling
- Operates across Toronto, GTA, Ottawa, Montreal, Vancouver, and Calgary

5. The Renovators of Canada
4.7 (75 reviews)score 81/100
The Renovators of Canada scores well for on-time, on-budget delivery, with project managers William, Jeff, and Cesar praised for staying accessible and fixing problems within hours. The composite score sits lower than peers here mainly because of one serious dispute worth weighing against the otherwise solid track record.
- Daily site updates and stage-by-stage cost tracking
- Named project managers stay accessible throughout
- Tradespeople singled out by name for skill and professionalism
- Upfront disclosure of quoted extras
Watch out: One reviewer reported an 8-month basement and bathroom job that tripled the original quote, with structural mistakes and subcontractor payment issues requiring a second contractor to fix.

6. X&H Construction
4.9 (60 reviews)score 85/100
X&H Construction earns a 4.9 rating from 60 reviews on the strength of its design department (Monica, Claire, Lee, Jacqueline) and detail-focused bathroom and kitchen work. Daniel's team finishes on schedule, charges transparently when scope changes, and one homeowner reported warranty follow-up years after the original job.
- Full-service design and build across kitchen, bath, basement, and whole-home
- Transparent pricing on change orders
- Site supervisor Marc keeps worksites clean with quick issue resolution
- Warranty follow-up honored years after project completion
Watch out: Pricing runs higher than competitors, and one project saw a mid-project designer handoff cause temporary friction.
