Price per square foot is a property's price divided by its interior floor area, and in Toronto it is the fastest way to judge whether a condo is priced fairly against comparable units. A 600 square foot suite listed at $700,000 works out to roughly $1,167 per square foot. Divide the price by the size and you have a number you can hold up against the building next door.
The calculation is simple. What complicates it is the square footage itself. Most Toronto listings quote interior space and leave the balcony, terrace, and locker out of the figure, though not every listing agent measures the same way. Two units advertised at an identical size can differ by fifty real square feet once you check the floor plan. So the number is a starting point, not a verdict.
Used well, price per square foot lets you weigh a one-bedroom in Liberty Village against one in the Distillery without getting distracted by the total sticker price. It travels across unit sizes, which raw price does not. A larger suite almost always carries a lower per-foot figure, because a kitchen and a bathroom cost about the same whether the unit is small or large, so that fixed cost spreads thinner over more space. Keep that in mind before you assume a compact studio is overpriced next to a two-bedroom down the hall.
The figure hides plenty. It says nothing about the view, the floor you sit on, the direction the windows face, or how usable the layout actually is. It skips upgrades entirely. It also ignores the monthly carrying cost, which is where condo maintenance fees quietly change the math on what a unit really costs to own. Pre-construction and newer buildings tend to command a higher per-foot price than older resale stock, so comparing across eras can mislead you.
Agents lean on it during a comparative market analysis, weighing recent sales per square foot in the same building or pocket to arrive at a price. It is also a different thing from the city's assessed value, which follows its own formula for property tax purposes. Treat price per square foot as one lens among several, never the whole picture.
