Weather Trivia
Greenstone’s location across the northern interior of Ontario makes it prone to sharp April temperature swings. Cold air can hold on longer here than in communities closer to Lake Superior, allowing flurries, ice pellets, and freezing drizzle to appear well into spring before warmer air finally pushes back in..
