Part of Thornhill is in Richmond Hill, but Thornhill is not a city of its own. Thornhill is a community that straddles two municipalities: its western half sits inside the City of Vaughan and its eastern half sits inside the Town of Richmond Hill, with a small portion in Markham. For buyers weighing Thornhill vs Richmond Hill real estate, that split identity affects taxes, schools, and transit. Here is how the two compare in 2026.
I've spent over 25 years helping buyers choose between these two communities, and I still field this question nearly every week. With $750M+ in GTA transactions and closings on both sides of Yonge Street, I can tell you the answer isn't one-size-fits-all. The decision framework, though, is clearer than most people expect.
Is Thornhill in Richmond Hill, Vaughan, or Markham?
Thornhill is in all three, which surprises most people. The western portion of Thornhill falls within the City of Vaughan, the eastern portion within the Town of Richmond Hill, and a small eastern slice within the City of Markham. Yonge Street is roughly the dividing line. Two neighbours on opposite sides of the same street can pay different tax rates and belong to different services.
This dual municipal footprint is the single most important thing to understand before you buy. It affects development levies, municipal services, transit funding, and the pace of intensification. If you're shopping near Yonge Street, confirm the exact municipal address before you make an offer, because the property tax rate and service structure change depending on which side of the line you land on. When I work with buyers along the Yonge corridor, verifying the municipality is step one, not an afterthought.
Is Thornhill a city?
No, Thornhill is not a city. It has no independent municipal government. It is an unincorporated community split between the City of Vaughan and the Town of Richmond Hill (plus a sliver of Markham). Richmond Hill, by contrast, is a fully independent municipality within York Region, running from the Oak Ridges Moraine in the north down to its border with Thornhill and Markham.
That structural difference matters for buyers. Richmond Hill sets its own tax rate, budgets its own capital projects, and plans its own intensification. Thornhill's future is shaped by two separate councils. For a closer look at how the neighbourhoods, land transfer tax, and buying process work across this area, the Thornhill and Vaughan real estate guide breaks it down from a broker based right on Yonge Street.
What is the Thornhill population in 2025?
Because Thornhill is not a single municipality, Statistics Canada does not publish one tidy population figure for it the way it does for an incorporated city. The number reflects two census tracts counted under two different municipalities.
How far is Thornhill from Toronto?
Thornhill borders Toronto directly at Steeles Avenue, so you are already in the GTA the moment you cross it. By car, downtown Toronto is roughly 25 to 40 minutes from central Thornhill depending on traffic and your exact starting point. By transit, Union Station is about 50 to 60 minutes door-to-door using York Region Transit buses to Finch Station and the Yonge-University subway.
Thornhill's eastern section sits closest to the subway, which gives it a real commuting edge today. The Bank of Canada overnight rate currently sits at 2.75%, which matters for anyone pricing out a commute-versus-carrying-cost trade-off. The Yonge North Subway Extension is the change both communities are watching: planned stations at Clark and Royal Orchard will sit inside Thornhill, while Langstaff and High Tech Road will serve southern Richmond Hill. You can model carrying costs before you book showings with the Canadian mortgage calculator.

In my recent Thornhill work, detached homes near Clark Avenue and Bathurst Street in the Thornhill Village area have moved briskly, often with multiple offers when priced sharply. Richmond Hill's most competitive pockets sit around Bayview Avenue south of Major Mackenzie, where newer builds and strong school catchments push demand. Richmond Hill's wider price band reflects its spread: the dense south near Yonge and 16th is a different market from the estate lots near Jefferson or Oak Ridges.

Which neighbourhoods should you look at in each community?
Thornhill's standout pockets are Thornhill Village, Bayview Glen, Crestwood-Springfarm-Yorkhill, and the Uplands area on the Vaughan side. Richmond Hill's are Mill Pond and South Richvale, the Langstaff and Yonge corridor, Bayview Hill, and Oak Ridges and Jefferson in the north. Each pocket trades at a different price point and suits a different buyer.
Thornhill
Thornhill Village, near Yonge and Centre Street, is one of the GTA's most charming pockets: heritage homes, walkable retail, and a mature tree canopy. Bayview Glen offers larger lots and sought-after school catchments for move-up buyers. Crestwood-Springfarm-Yorkhill gives families more accessible entry points with good Catholic school access. Uplands and the Dufferin-side pockets draw buyers priced out of the east side, though taxes differ by municipality, so verify with your real estate lawyer before you offer.
Richmond Hill
Mill Pond and South Richvale is Richmond Hill's prestige address: custom homes on large lots, walkable to Mill Pond park. The Langstaff and Yonge corridor is intensifying fast and sits in the subway extension's path, making it the town's most forward-looking investment pocket. Bayview Hill is consistently among York Region's top school catchments. Oak Ridges and Jefferson, backing onto the moraine, offer more space and a semi-rural feel, usually at lower prices than comparable homes in the south, with a longer commute as the trade-off.
Schools, lifestyle, and community feel
Both communities are served by the York Region District School Board and the York Catholic District School Board, and York Region consistently outperforms the Ontario provincial average on EQAO assessments. Specific catchments still drive buying decisions, so school quality is high across both Thornhill and Richmond Hill, but the exact boundary matters.
When my clients compare semis or condos across the two markets, school catchment is almost always the first filter they apply. In Thornhill, Alexander Mackenzie High School and St. Elizabeth Catholic High School are well-regarded. In Richmond Hill, Bayview Secondary and Richmond Hill High School are perennial performers. Always confirm current boundaries directly with the boards, since they shift with new development. For rankings, the Statistics Canada census profiles are a reliable starting point for demographic context.
Thornhill feels established, with much of its housing built from the 1970s through the 1990s: large trees, settled community associations, and the Promenade Shopping Centre as a hub. Richmond Hill feels more dynamic, especially in its south and centre, with the Richmond Hill Centre for the Performing Arts and a transforming downtown around Yonge and Major Mackenzie. Both are highly multicultural. Thornhill has a particularly large Persian-speaking community, one reason I've been privileged to serve so many Farsi-speaking clients there. Buyers who prefer to work in Farsi can read more about Farsi-language real estate service in the GTA.
Which suburb should you buy in for 2026?
Choose Thornhill if you commute daily by transit to downtown Toronto and want a mature, walkable neighbourhood at a slightly lower detached entry price. Choose Richmond Hill if you drive, work hybrid or remote, want more space for your dollar, and like buying into a market with active intensification along the Langstaff corridor. Both have strong resale histories; one usually fits your daily life better.
When I sit down with a buyer comparing the two, my first question is simple: what does your Tuesday morning look like? How you commute, whether you have kids in school, and whether you want a turnkey home or a project matter more than any macro comparison. I can't promise appreciation in either market, but the transit pipeline and development runway suggest both have long-term demand support.
