Ontario Road Trip: The Ultimate Route from Toronto to Thunder Bay
Ontario isn’t just Canada’s most populous province—it’s also home to some of the country’s most dramatic landscapes. A road trip from Toronto to Thunder Bay takes you from urban skylines to rugged wilderness, winding past charming towns, pristine lakes, and breathtaking views of Lake Superior. Whether you’re craving outdoor adventure, cultural stops, or just the freedom of the open road, this journey offers it all.
Why This Road Trip?

You’ll pass through Muskoka’s cottage country, skirt Georgian Bay’s rocky shores, and hug the northern edge of Lake Superior—a drive widely regarded as one of the most scenic in Canada.
