Toronto's Size: Square Kilometres, Not Acres

The City of Toronto's land area is officially measured in metric units: approximately 630 square kilometres (243 square miles). While acres are used for individual properties or parks, municipal boundaries are not expressed in acres.

Putting It in Perspective

• 630 km² = ~155,676 acres (for reference only).
• Toronto is the fourth-largest city by area in Canada (after La Tuque, QC; Senneterre, QC; and Rouyn-Noranda, QC—all vast northern municipalities).
• The Greater Toronto Area (GTA) spans ~7,125 km² (5.5 million people).

Why Not Acres?

Canada has used the metric system officially since the 1970s. Government surveys, planning documents, and legal descriptions use hectares (1 ha = 2.47 acres) or square kilometres. Real estate listings may mention acres for large lots, but the city's total area is never cited that way.

If you need the acre equivalent for a specific calculation: 630 km² × 247.105 = ~155,676 acres.
