About this place
Markham is a large suburban city directly north of Toronto, offering a blend of modern high-tech living and well-preserved 19th-century heritage. Its population of roughly 340,000 reflects a diverse, multicultural community with a strong Chinese influence, particularly noticeable in the local food scene.
Three distinct heritage districts anchor the city’s historical character. Main Street Unionville is the most quaint, with period buildings housing eateries and boutiques, while Main Street Markham (Markham Village) mixes heritage structures with a broader retail selection. Thornhill offers a smaller, purely residential cluster of historic homes.

Things to See
- Main Street Unionville — a heritage conservation district where elegant 19th-century houses and a former railway station now host pubs, eateries, and tourist-oriented shops along a quaint main street.
- Main Street Markham (Markham Village) — a pleasant retail and residential strip extending from Highway 7 to 16th Avenue, featuring a mix of heritage buildings and modern structures with more shopping options than Unionville.
- Thornhill heritage district — a picturesque residential area along Colborne Street with over a dozen 19th-century homes, many with white picket fences, ideal for a brief stroll rather than a day trip.
- Stiver Mill and Unionville station — located just north of the railway crossing on Station Lane, these historic buildings now serve community functions and add to Unionville's old-town charm.

Planning Tips
- Transit from Toronto — if you're not driving, most trips start at Finch Station on TTC Line 1; for Pacific Mall, take TTC bus #53 Steeles East; for Unionville, transfer to Viva Purple or YRT bus 1 at Richmond Hill Centre Terminal.
- Navigate 'Main Street' carefully — 'Main Street Markham' (Markham Village) and 'Main Street Unionville' are separate areas over 4 km apart; confirm which one you're entering to avoid missed connections.
- Avoid Highway 407 in a rental — the electronic toll road sends an inflated bill to the vehicle's owner; use Highway 7 or Highway 401 instead.
- Parking for Unionville — if driving to the heritage district, parking is available off Carlton Road on the south side, east of Main Street.
