Renovation Contractors in Toronto
When it comes to home renovation Toronto, no two homes are alike — the city’s housing is as layered as the city itself, from century semis and Victorians downtown to the character homes of the Beaches, Leslieville and High Park. GMC Construction Inc. has spent 15+ years working across all of them — kitchens, bathrooms, basements and whole-home renovations for Toronto homeowners who want the job planned properly, priced honestly, and built to last.
What sets us apart in a crowded market: GMC is led by an owner who holds a Master’s degree in Structural Engineering. Before we quote a wall removal, a basement underpinning, or a third-floor addition, we understand how the house actually carries load — which is why our projects don’t run into the structural surprises that stall other renovations. It’s a structure-first approach no other Toronto renovation company offers, and it matters especially in the city’s older, narrower homes.
Our Renovation Services in Toronto
Kitchen Renovations
Custom cabinetry, islands and full layout changes — from a narrow galley in a Leslieville semi to an open-concept kitchen in a Beaches home.
Bathroom Renovations
Ensuites, main baths and powder rooms with proper waterproofing — essential in Toronto’s older homes and condo units alike.
Basement Renovations
Finished basements, underpinning for extra height, and legal secondary suites — a proven way to add space and rental income in Toronto’s tight housing market.
Home Additions
Rear and third-floor additions, dormers and garden suites — the projects where the owner’s structural engineering education matters most.
Whole-Home Renovations
Complete transformations that modernize an older Riverdale or High Park home top to bottom — one coordinated project, one point of contact.
Condo Renovations
Downtown and waterfront condo renovations — managed around board approvals, elevator bookings and the restricted work hours Toronto buildings require.
Renovating in Toronto: What to Know
Toronto’s older housing brings renovation realities you won’t find in newer suburbs. The century semis and Victorians of downtown, the east end and midtown are full of character but often have knob-and-tube wiring, original plumbing, shallow basements and load-bearing walls in awkward places — which makes structural planning essential before any open-up or addition. Basement underpinning to gain ceiling height and legal secondary suites are especially popular given Toronto’s housing costs. Condos across the downtown and waterfront come with their own board rules, elevator bookings and strict work-hour windows.
Because so many Toronto homes are narrow, attached, and over a century old, getting the structure right is not optional — it’s the difference between a renovation that goes smoothly and one that uncovers expensive surprises. That’s exactly where our structure-first approach protects your timeline and budget.
Do You Need a Permit to Renovate in Toronto?
Renovation permits in Toronto are issued by Toronto Building (City of Toronto). Cosmetic work — replacing cabinets, tile, fixtures and finishes in the same layout — generally doesn’t require a permit. But moving plumbing, altering electrical, removing a load-bearing wall, underpinning, finishing a basement, adding a legal second suite or garden suite, or building an addition typically do — and additions or variances may involve the Committee of Adjustment. Heritage-designated properties carry extra review. As a licensed contractor, GMC manages the Toronto permit process for you and works with a licensed professional engineer for any stamped structural drawings your project requires.
