Eastern Ontario
Eastern Ontario's climate is heavily influenced by the proximity of the Great Lakes and its relative northern latitude compared to other parts of Southern Ontario. Winters in the region are typically severe, with regions experiencing low temperatures and significant amounts of snow and ice during winter months. Highland regions experience more severe winters due to their higher elevation. Significant snowfall is common in the area even into the spring. Summers are typically hot and humid in lower-lying areas, with milder and cooler summers occurring in the north. Eastern Ontario also experiences ice storms on a regular basis due to the presence of the arctic high-pressure system, heavily impacting the low-lying areas of the Ottawa Valley and St. Lawrence Valley, with significant events including the 1998 North American Ice Storm and the 2023 Canadian Ice Storm. Eastern Ontario also regularly experiences severe weather events, including tornadoes, and thunderstorms as a result of humid summer temperatures.

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…
