City of Markham · York Region · Ontario

Understand Markham before you commit to an address

Markham is 338,000 people, the largest concentration of technology employment in the country outside downtown Toronto, and one of the most diverse municipalities in Canada by any measure you choose. It also publishes the lowest residential tax rate of any municipality in this layer. The figures here come from two tables measured the same way in all 24 municipalities around Toronto: the board's own price index and the province's own tax return. The rent is a Toronto-wide figure rather than a local one, because nobody surveys rents municipality by municipality here.

Before the arithmetic

What buying in Markham actually involves

That low rate is the layer's clearest illustration of what a rate does and does not tell you. Markham's own levy is 0.17% and York Region's is more than twice that, so the council with the low rate controls a quarter of the bill. And because Markham's prices have risen less since 2016 than most of the region's, the rate charged against a frozen assessment converts into a middling effective rate on what a house actually costs today.

Unionville and the older parts of Thornhill are a different market from the subdivisions and the towers around Highway 7. The city-wide benchmark on this page averages across all of them, which is worth remembering before you compare it against a listing.

Check these before you commit

  • Which school catchment the address is in, because this is one of the region's most actively shopped-for factors and the boundaries move
  • Whether a townhouse is freehold or condominium, since both are common here and the monthly cost is not
  • The GO Stouffville line's service level from the specific station, which varies more than the map suggests
  • For older Unionville property, whether it sits inside the heritage conservation district

The rent shown on these pages is CMHC's Toronto CMA average rather than a figure for this municipality, because the survey's zones are not municipal boundaries. It is marked as regional everywhere it appears and it is not a comparison between the places in this layer.

03, Where the numbers come from

Sourced, dated, and separated from the guesswork

The calculators open with real Markham figures: the benchmark price, market rents, the property tax rate this city actually levies: each one cited and stamped with the period it describes. Every one of them is an editable input, because a figure that describes the whole city rarely describes your purchase.

Forward-looking rates are a different kind of number. Appreciation, rent inflation and investment returns are assumptions, not facts, and they are labelled that way wherever they appear. Read the research and sourcing methodology for how the line is drawn.
