Built to Last — Not Just Installed

What makes us different starts before the first material is ordered. GMC Construction is founded and led by an owner who holds a Master's degree in Structural Engineering — so every project is approached with a genuine, advanced understanding of structure, load-bearing changes, drainage, and moisture protection. Most renovation companies focus only on how a space looks. We start with what's underneath, because that's what determines whether your renovation lasts five years or twenty-five.

Renovation Contractors in North York

When it comes to home renovation North York, no two homes are alike — from the postwar bungalows of Willowdale and Bathurst Manor to the executive homes of York Mills and the condos rising along Yonge, each renovates differently. GMC Construction Inc. has spent 15+ years working across all of them — kitchens, bathrooms, basements and whole-home renovations for North York 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 second-storey 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 North York renovation company offers.

Finished basements, legal secondary suites and lower-level living space — a common way to add space and rental income in North York’s older homes.

Home Additions

Second-storey additions, rear extensions and garage conversions — the projects where the owner’s structural engineering education matters most.

Condo and townhome renovations along the Yonge and Sheppard corridors — managed around board approvals, elevator bookings and restricted work hours.

Renovating in North York: What to Know

North York’s housing stock is dominated by solid postwar construction, and that shapes most projects here. The bungalows, side-splits and back-splits of Willowdale, Newtonbrook, Bathurst Manor and Don Mills are structurally sound but often have compartmentalized 1950s–60s layouts — which makes them ideal candidates for opening up the main floor, adding a second storey, or finishing the basement into a suite. The executive homes of York Mills, Hoggs Hollow and Lawrence Park North frequently see full modernizations and high-end additions. And along Yonge and Sheppard, condo renovations come with their own building rules.

Because so many North York homes sit on generous lots with original layouts, second-storey additions and major structural open-ups are especially common here — exactly the work where a structure-first approach protects your timeline and budget.

Do You Need a Permit to Renovate in North York?

North York is part of the City of Toronto, so renovation permits are issued by Toronto Building, not a separate municipality. 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, finishing a basement, adding a legal second suite, or building an addition typically do, and Toronto’s Committee of Adjustment may be involved for variances on additions. As a licensed contractor, GMC manages the Toronto permit process for you and arranges the stamped structural drawings your project requires.

Under Bill 23, a basement second suite is now permitted as-of-right in most Toronto residential zones — with no minor-variance application, no added parking requirement, and no development charges for the second unit. The suite still has to meet Toronto Zoning By-law 569-2013, the Ontario Building Code, and the Fire Code together. The most common hurdle in older North York homes is ceiling height — roughly 1.95 m over at least 75% of the area — which is why many pre-1960 basements need underpinning to qualify. Electrical work is permitted separately through the ESA.

frequently asked questions

Do I need a permit to renovate my home in North York?

North York is part of the City of Toronto, so permits are issued by Toronto Building. Cosmetic updates — new cabinets, tile, fixtures or finishes in the same layout — usually don't need a permit. But moving plumbing, changing electrical, removing a load-bearing wall, finishing a basement, adding a legal second suite, or building an addition require a Toronto Building permit, and additions may involve the Committee of Adjustment. As a licensed contractor, GMC handles the entire permit process for you.

How much does a renovation cost in North York?

It depends on scope and finishes. As a guide, bathroom renovations typically run $16,000–$28,000, kitchens $25,000–$60,000, and finished basements $35,000–$70,000, with whole-home and addition projects quoted individually. After a free in-home consultation we give you a detailed, fixed-price quote — the real number, with no vague allowances.

How long does a renovation take in North York?

Timelines depend on scope. A bathroom typically takes 3–6 weeks, a kitchen 4–8 weeks, and a basement 6–10 weeks, while whole-home renovations and additions run longer — especially when a Toronto Building permit is required, since municipal review adds time. We give you a week-by-week schedule before work begins so you always know what to expect.

Can you remove a load-bearing wall in my North York home?

Yes — and this is where our approach stands apart. GMC is led by an owner who holds a Master's degree in Structural Engineering, so we assess how your home carries load before touching a wall, and arrange the stamped structural drawings and permit the work requires. Opening up a compartmentalized postwar layout is one of the most common — and most structurally sensitive — requests we handle across North York.

Which North York neighbourhoods do you work in?

All of them. We renovate homes across Willowdale, Newtonbrook, Bathurst Manor, Bayview Village, Don Mills, Banbury, York Mills, Hoggs Hollow and Lawrence Park North — from postwar bungalows to executive homes and condos along Yonge and Sheppard. We serve North York daily.

Why choose GMC over other North York renovation companies?

GMC is led by an owner who holds a Master's degree in Structural Engineering, so every project is planned around how your home actually carries load — the structural surprises that stall other renovations get caught up front. Combined with fixed-price quotes, a written workmanship warranty, and a 5.0-star rating across 85+ Google reviews, that gives you a level of confidence most renovation crews can't match.
