Frequently asked questions

On average, new builds in Toronto run roughly $300–$400 per square foot for a good-quality home. That means a 2,000 sq ft house might cost $600,000–$800,000 just for construction. Luxury custom homes with high-end finishes can go higher. Land, permits, design fees, and HST are extra.

Toronto real estate has historically grown in value because of strong demand, immigration, and a limited housing supply. While there can be market dips, people who hold their property for the long term typically benefit from both appreciation and rental demand. The challenge is affordability—prices are high and mortgage rates affect buying power—so it’s important to plan for the long haul.

It depends on your goals:

  • Detached homes offer privacy, space, and the best resale value but cost more.

  • Semi-detached, townhomes or multiplexes are cheaper to build and align with city policies encouraging more units on one lot.

  • In colder climates, good insulation and energy-efficient designs are critical no matter the style.

A straightforward new build usually takes 6–12 months once permits are in place. A full custom home can take closer to 12–18 months because of design work and permitting. Weather, trades availability, and the complexity of the project all affect timelines.

Toronto property can be a solid investment thanks to steady demand and limited land. Rental markets are strong too. But it’s not risk-free: prices are high, and there can be corrections. It makes the most sense if you have a long time horizon and can comfortably carry costs even during slow markets.

Not really. A semi shares a wall with the neighbor; separating it would mean major structural changes and likely zoning challenges. If you want a fully detached home, it’s better to buy one or rebuild on a lot zoned for it.
