Snow in Ontario
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
In mid-November 2009, a band of snow stretched across Ontario between James Bay and Lake Superior. North of Lake Superior, Lake Nipigon interrupted the broad band of snowy white. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this true-color image on November 18, 2009. Snow cover appears thickest near James Bay, gradually tapering off toward the southwest.
Average annual snowfall in Ontario ranges from 200 to 400 centimeters (80 to 160 inches), with the greatest accumulations usually near Lake Superior.
