Thornhill Homes for Sale
Markham-side Thornhill — Royal Orchard, Bayview Glen, Grandview, Aileen-Willowbrook, German Mills. Premium detached inventory east of Yonge.
Thornhill is one of the GTA's few neighbourhoods that genuinely spans two municipalities. Yonge Street is the dividing line: Vaughan on the west side, Markham on the east. This page covers the Markham-side six sub-communities — Thornhill (the core), Royal Orchard, Bayview Glen, Grandview, Aileen-Willowbrook, and German Mills. If you're looking for the Vaughan side (Beverley Glen, Uplands, Crestwood-Springfarm-Yorkhill), see /thornhill-vaughan-homes-for-sale.
The Markham-side character is distinct from the Vaughan side. Royal Orchard and Bayview Glen are the luxury anchors — 50–80 ft lots, established mature streetscapes, custom-rebuild pipeline active since the 2010s. Grandview and Aileen-Willowbrook are the family-suburban middle tier at $1.5M–$2.5M detached. German Mills is a smaller pocket close to the Leslie Street corridor. The sub-communities share strong public school catchments (Thornlea SS, Henderson Avenue PS), Yonge-Steeles amenity density, and a 10-minute drive to either Highway 7 or the 407.
Listings below are every active MLS freehold match across the six Markham-side Thornhill sub-communities right now, pulled live from the TRREB feed. Condo inventory is excluded by design — see /properties with explicit filters for condo searches.

Which Markham-Thornhill sub-community fits?
Royal Orchard sits at the north end, centred on John Street — planned in the 1960s–70s as an upscale detached community, with mature tree canopy and consistent 55–75 ft lots. Trades $2M–$4M for typical family homes with premium streets reaching $5M–$6M+. Bayview Glen is the southern luxury anchor along Bayview just north of Steeles — similar lot sizes to Royal Orchard, slightly newer custom-rebuild density, and comparable pricing. Grandview and Aileen-Willowbrook form the family-suburban middle at $1.5M–$2.5M on 40–55 ft lots — strong entry points for move-up buyers. German Mills is a small southwest pocket, older 1970s–80s housing stock, meaningful renovation opportunity.
For buyers torn between Markham-Thornhill and Vaughan-Thornhill: the Markham side is typically slightly pricier for comparable square footage (Bayview Glen vs Beverley Glen, for example), has distinctly stronger school catchment options (Thornlea + Bayview SS overlap in places), and tilts more toward established detached luxury. The Vaughan side has Crestwood-Springfarm-Yorkhill's quieter family profile and is often $100K–$300K more accessible at the family-detached tier.
Thornhill — frequently asked
What's the difference between Markham-side and Vaughan-side Thornhill?
Yonge Street divides them geographically. Markham-side (this page) covers Royal Orchard, Bayview Glen, Grandview, Aileen-Willowbrook, German Mills, plus the Thornhill TRREB region itself — east of Yonge. Vaughan-side (/thornhill-vaughan-homes-for-sale) covers Beverley Glen, Uplands, Crestwood-Springfarm-Yorkhill — west of Yonge. Similar school catchment strength, similar commute geography, but trade as meaningfully different markets. Markham-side is typically slightly pricier and has more established luxury detached; Vaughan-side has more consistent family-suburban character.
How much does a home in Markham-Thornhill cost?
Varies widely by sub-community. Royal Orchard and Bayview Glen — the luxury anchors — trade $2M–$4M for established family detached, reaching $5M–$6M+ for premium streets and custom rebuilds. Grandview and Aileen-Willowbrook run $1.5M–$2.5M for mainstream family detached. German Mills offers more accessible entry at $1.3M–$1.7M with renovation upside. Overall the page covers six distinct sub-markets — the community pages below break them apart further if you want more granular pricing.
Are Markham-Thornhill schools good?
Above York Region median, with specific strong pockets. Thornlea Secondary School is the main public catchment high school and has consistently solid EQAO results. Henderson Avenue PS and E.J. Sand PS are well-regarded catchment elementaries. Parts of the Bayview Glen area fall into St. Robert Catholic HS catchment — one of Ontario's top-ranked Catholic secondaries. The overall school profile is a significant driver of Markham-Thornhill's firm pricing.
What's the commute from Markham-Thornhill?
Highway 407 access at Leslie or Bayview is 5 minutes. Highway 404 is 8 minutes east. Downtown Toronto by car is 35–55 minutes off-peak. Richmond Hill GO (Langstaff station) is 10 minutes north — peak service to Union in 40 minutes. The Yonge North Subway Extension (2031 target) will add three stations within Richmond Hill that are 5–10 minutes drive from most of Markham-Thornhill.
Does this page include condos?
No — this page is filtered to freehold only (detached, semi-detached, townhouse). The Yonge Street corridor running through Thornhill has substantial condo inventory, but the page copy and target intent is "homes for sale" in the family-freehold sense. For condo searches, use /properties with filters for Markham condos, or ask — I can point you at the specific Thornhill condo buildings worth considering.
