Thunder Bay – Travel Forecast – If you’re planning a springtime road trip from Toronto to Winnipeg, you’re in for a mix of sunshine, warmth, and — true to Canadian form — a little cold air drama. As May kicks into gear, your journey across Ontario into Manitoba offers beautiful driving conditions, with mostly dry roads, clear skies, and plenty of sunshine.
But don’t let the blue sky fool you: from frosty mornings in Thunder Bay to gusty prairie winds in Winnipeg, this route demands smart packing and a few planned pit stops.
As of this morning, 511 Ontario is reporting good driving conditions along Highways 401, 17, and 11, with no major closures or weather-related hazards along the Toronto-to-Kenora route.
Fog patches around Thunder Bay and Geraldton are expected to dissipate early, but visibility may be reduced in some low-lying areas. Winds will pick up significantly in western Ontario and Manitoba, particularly near Dryden, Kenora, and into Winnipeg, where gusts could reach 60 km/h.
If you’re driving a high-profile vehicle or towing a trailer, extra caution is advised.
Your journey starts in Toronto, where light rain and gusty east winds (up to 40 km/h) will greet you by the afternoon. High: 15°C. You’ll move north into Sudbury, where the skies clear beautifully and the temperature climbs to a mild and sunny 15°C. A great day for hitting the road — but don’t forget your umbrella for the Toronto leg.
