Halton Region topographic map

Despite its deep ravines, Toronto is not remarkably hilly, but its elevation does increase steadily away from the lake. Elevation differences range from 76.5 metres (251 ft) above sea level at the Lake Ontario shore to 209 m (686 ft) ASL near the York University grounds in the city's north end at the…

London has a humid continental climate (Köppen Dfb), though due to its downwind location relative to Lake Huron and elevation changes across the city, it is virtually on the Dfa/Dfb (hot summer) boundary favouring the former climate zone to the southwest of the confluence of the South and North Thames Rivers,…

Peterborough's topography is largely defined by land formations created by the receding Wisconsian glaciers 10,000–15,000 years ago. The South End and Downtown portions of the City sit on what was the bottom of the glacial Lake Peterborough—part of a glacial spillway created when glacial meltwaters from…
