What is the shortest route from phoenix AZ to Toronto Ontario?

Answer 1

Toronto to Phoenix by car:

Take the QEW to the Peace Bridge, then pick up I-190 at the other end of the bridge in Buffalo to I-90. I-90 will take you to Cleveland and I-71. Take I-71 to Columbus, then I-70 to St Louis, where you transfer to I-44. I-44 will take you to Oklahoma City where you pick up I-40. Follow I-40 all the way to Flagstaff, Arizona, then I-17 will take you right into Phoenix.

DO NOT CROSS AT DETROIT.

A slightly longer alternative is the QEW, 403, 401 and 402 combination to Sarnia, where you cross to Port Huron. Then take I-69 to Indianapolis where you pick up I-70 and continue as above.

Answer 2

I-17 North to Flagstaff.

I-40 East to Tucumcari.

US-54 North to Wichita.

I-35 North to Cameron.

US-36/I-72 East to Springfield.

I-55 North to I-80 East to I-94 East to I-69 North.

Cross the border at Sarnia.

402 to 401 to 403 will take you into Toronto.

That's the shortest distance. Taking I-40 East to Oklahoma City, I-44 East to St. Louis, I-70 East to Indianapolis, I-69 North to I-469 around Fort Wayne, US-24 East to Toledo, I-75 North to Detroit, cross the border and take 401 to 403 to Toronto is an hour faster.
