Radius Map of Toronto

The map above is centered on Toronto, Canada, near Yonge & Bloor, with a default 15 km radius. Drag to move it, search for a different address, or change the radius and unit using the controls.

Toronto is the dense core of a long, linear metropolitan area along Lake Ontario's north shore. A 15 km radius from Yonge and Bloor reaches the inner GTA — Etobicoke, North York, Scarborough — but stops short of Mississauga (the second city of the GTA), Markham, or Brampton. For full GTA reach, use 25–35 km radii. Lake Ontario eats the entire southern arc of any Toronto radius.

Population: 2.9 million city / 6.4 million GTA

Time zone: America/Toronto

The Greater Toronto Area stretches roughly 100 km along Lake Ontario's north shore — Burlington in the west to Oshawa in the east. A 15 km radius from Yonge & Bloor reaches the inner GTA but stops short of Mississauga or Markham.

How Toronto radius maps get used

City-specific scenarios where a radius is the right tool — and the typical radius sizes professionals use.

Inner GTA condo search

Toronto condo hunters often use a 10 km radius from Yonge and Bloor or another central node to filter for transit-rich, walkable inner-city units. Beyond 10 km, the GTA becomes more car-dependent and the condo market gives way to townhouses and detached homes.

Typical radius: 10 km for transit-rich inner Toronto

Pearson Airport service planning

Pearson sits about 22 km west of Yonge and Bloor — outside a 20 km radius but inside 25 km. Hotel and ground-transport operators use a 25 km radius as the airport-inclusive zone for shuttles and tariff cards.

Typical radius: 25 km for Pearson-inclusive zones

GTA-wide retail trade area

Big-box retail in Toronto routinely defines a 25–35 km primary trade area to capture the dense suburban GTA — Mississauga, Brampton, Vaughan, Markham, and Scarborough collectively house more than 4 million people. A 35 km radius covers most of them.

Typical radius: 25–35 km for full GTA retail catchment

Hamilton and Greenbelt commuter analysis

Hamilton (60 km southwest) and Oshawa (55 km east) are GO Transit commuter towns but sit at or beyond the edge of a 50 km radius. Real-estate analysis of these towns should account for GO Train travel time (typically 60–80 minutes) rather than driving distance alone.

Typical radius: 50 km plus GO Train awareness

Geographic quirks of Toronto radius mapping

Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.

Lake Ontario eats the southern arc

Lake Ontario sits directly south of Toronto, so the southern half of any radius drawn from the CBD is over water. For population, retail, and service-area math, always use the land-area inside the circle — typically 50–60% of the raw circle.

The GTA is linear, not circular

The Greater Toronto Area extends roughly 100 km east-west along Lake Ontario but only 30–40 km north before hitting the Greenbelt. A circular radius distorts this — a 50 km radius covers the western and eastern GTA fine but reaches well beyond the typical northern commuter limit.

Highway 401 is the GTA's spine

Ontario Highway 401, running east-west across the top of Toronto, is the busiest highway in North America and the practical axis of the GTA. Service-area planning often uses "north of the 401" or "south of the 401" as a divider — a useful binary that radius alone doesn't capture.

FAQ — Radius mapping in Toronto

How big is a 15 km radius in Toronto?

A 15 km radius from Yonge and Bloor covers most of the City of Toronto post-amalgamation — Etobicoke, North York, East York, and Scarborough's western half — but stops short of Mississauga (~22 km), Markham (~18 km city centre), and Vaughan main.

What's within 25 km of Toronto?

A 25 km radius covers all of the City of Toronto plus Pearson Airport, the eastern half of Mississauga, the southern halves of Vaughan and Markham, Pickering, and most of Scarborough. Hamilton, Oshawa, and Niagara are well outside.

Does a 25 km radius cover Pearson International Airport?

Yes. Pearson sits about 22 km west of Yonge and Bloor — comfortably inside a 25 km radius but outside a 20 km one. A 25 km radius is the standard airport-inclusive zone for hotels and ground transport.

How does the GTA differ from the City of Toronto on a radius map?

The City of Toronto fits inside roughly a 15 km radius; the Greater Toronto Area extends to 50+ km in the east-west axis (Burlington to Oshawa is about 100 km). A 25 km radius captures the dense inner GTA; a 50 km radius captures most of the GTA except the Hamilton and Niagara extensions.

Why does a Toronto radius feel half the size of a Chicago radius?

Largely because Lake Ontario takes the entire southern half. Toronto and Chicago are both lakefront cities, but Toronto's downtown sits right on the lake while Chicago's Loop is set back slightly. A radius from each city loses roughly 50% to water on average, but Toronto's loss is more concentrated on one side.

How do I plan a GTA-wide retail catchment?

Use a 25–35 km radius from your store location, then use the Drive Time Map to validate the catchment given Highway 401 and 400-series traffic at peak hours. Mississauga, Brampton, Vaughan, Markham, and Scarborough collectively house most of the GTA's 6.4 million people; a 30 km radius from central Toronto reaches all five.
