Thornhill's demolition contractor. Actually from Thornhill.

Depends on your side of Yonge Street. West of Yonge you're in the City of Vaughan, permits go through Vaughan's Building Standards department. East of Yonge you're in the City of Markham, permits go through Markham's Building Standards. It trips up homeowners (and plenty of contractors) constantly. Tell us your street and we'll tell you which office you're dealing with and what they typically ask for.

Many do. Much of Thornhill's housing stock. The back-splits and bungalows around Royal Orchard, Thornhill Village, and German Mills. Went up in the 1960s–70s, when asbestos was common in flooring, plaster, insulation and duct wrap. Ontario requires testing of suspect materials before demolition disturbs them. We flag honestly and sequence abatement first when it's needed.

The same as our posted York Region ranges: $2–$7 per square foot for strip-outs, $1,000–$3,500 for a typical kitchen, $800–$2,500 for a bathroom gut. Thornhill-specific factors: plaster walls in older Village-area homes add disposal weight, and narrow side yards on mature lots can change how we stage bins.

It's one of the GTA's most active teardown markets. Mature lots on streets like those around Bayview Glen, Uplands, and old Thornhill Village carry land value that outweighs the original 1960s house, so bungalow-to-custom-home rebuilds are constant. If you're buying to rebuild, get the demolition number and permit path costed before you close. We do those assessments from listings and photos.

Yes. The Thornhill Heritage Conservation Districts (both the Markham and Vaughan sides of the old village core, around Yonge and Centre Street) have extra rules. Demolishing or substantially altering a structure there involves heritage review before a permit is issued, which adds real time. If your property is in the district, start the paperwork months ahead, not weeks.

We're based here. Small jobs such as sheds, concrete pads and kitchen gut-outs can often be scheduled within days, and quoting is usually same-day because we don't have to truck anyone in to look at it.

Plan on months, not weeks, if your property sits inside the Thornhill Heritage Conservation District around Yonge and Centre Street. Both Markham's and Vaughan's coordinated HCD plans require a heritage review before the building department will issue a demolition or major-alteration permit, and that review runs separately from, and typically ahead of. The standard permit process. Start the conversation with the city as early as possible; we'll tell you honestly whether your address falls inside the district boundary.

It can. Properties backing onto the German Mills Creek ravine system may fall inside a Toronto and Region Conservation Authority (TRCA) regulated area, which can require a separate TRCA permit for any work near the watercourse or top-of-bank, on top of, not instead of, the city's building permit. We don't file that paperwork, but we'll flag it on the first call if your lot looks close enough to matter, so it's not a surprise mid-project.

Survey and asbestos/designated-substances testing first, then permits (city building permit, plus heritage or TRCA review if your address requires it), then utility disconnection, then the physical demolition, structure and foundation out, lot rough-graded and compacted for the new build. On a typical Thornhill lot that sequence runs a few weeks for paperwork and a few days for the physical teardown itself. Full walkthrough on our house demolition page.

Neither office is dramatically faster in every case, both process straightforward permits (garage, interior, concrete) in a similar window, and both add real time when heritage review or a conservation-authority sign-off is in the mix. The practical difference is the paperwork and the reviewers, not the speed. Tell us your address and we'll tell you which office you're in and what a realistic timeline looks like before you start filling out forms.
