trishica, it depends which city in Ontario you move to.
If you are moving to, let's say, Thunder Bay, Sudbury, or generally anywhere north of Barrie, travel thru Canada. My own personal experience is that Hwy 1 is faster and more scenic than #3, but there is no difference once you hit Medicine Hat. You have no reason, whatever to take the Yellowhead. (#16)
When you arrive to Winnipeg, you can give me a call.
Along the way, in Ontario, (now you are on Hwy 17/11) you find a delightful and rustic "fort" in Vermillion Bay. Just North of Thunder Bay, the Niagara of the North, Kakabeka Falls. You can decide at Nipigon if you want to take #11 - if yes, prepare for long distances between stops. If you take #17, make sure you hit the North Shore of Superior at day time. The scenery is worth it.
However, if you move to Toronto, or anywhere east or south of Toronto, travel thru the States. All freeways, no traffic lights from Vancouver to the Border crossing. Take I5 to I90. At Billings, Montana, you will have a choice of staying on I90 or take I94. Both will take you thru Chicago. Then I94 to Detroit and 401 into Ontario. Along I90 you can take a small detour to visit DEvil's Mountain, scene of the alien landing in the movie, Close Encounters Of The Third Kind. Or make stop at Wall Drug Store, in Wall, SC a 19th century style "mall". Or take a short detour to Mount Rushmore and/or visit the Badlands. When you are in Wisconsin, don't forget to buy cheese.
Good luck travelling! And don't forget to make frequent stops.
