What it costs to buy in Unionville
Land transfer tax
Unionville is outside the City of Toronto, so buyers pay only Ontario’s land transfer tax, not the extra Toronto municipal tax. Here’s what that looks like at typical prices:
| Example purchase | Ontario LTT | First-time buyer pays |
|---|---|---|
| Detached home at $1,450,000 | $25,475 | $21,475 |
| Townhouse at $700,000 | $10,475 | $6,475 |
First-time buyers can get a refund of up to $4,000 on the Ontario land transfer tax. You (and your spouse) must never have owned a home anywhere in the world. Land transfer tax is paid on closing, on top of your down payment.
Property taxes
Markham’s residential property tax rate is 0.723% (2026 rate, City of Markham), or about $723 a year for every $100,000 of assessed value. In Ontario, property tax is based on your home’s MPAC assessed value, which is still based on January 1, 2016 values and is usually well below today’s market price.
| MPAC assessed value | Approximate yearly property tax |
|---|---|
| $400,000 | $2,892 |
| $600,000 | $4,338 |
| $800,000 | $5,784 |
| $1,000,000 | $7,230 |

Schools and family life

Markham Stouffville Hospital (Oak Valley Health) serves the area.
Child care
At licensed centres enrolled in the Canada-wide Early Learning and Child Care program, fees for children under 6 are capped at $22 a day in 2026, and families with lower incomes can apply for a fee subsidy. (The $10-a-day average has not yet been reached in Ontario.)
York Region’s Early Years Program Finder lets you search licensed centres, including those in the reduced-fee program and those offering subsidized spaces, plus EarlyON drop-in centres.
My tip: get on waitlists as early as possible, ideally several months before you move or before parental leave ends.
