I have never driven from Toronto to Vancouver, can you please let me know what to expect in Dec. How long? how many miles? driving conditions? Will i need snow tires? I have driven in winter conditions before, just never made the trip.
thanks

Do you realize this is thousands of miles through vst aeas where ther could be very serious snow?

It is six hours by plane and approximately five good driving days with good road conditions (10 plus hours a day). The roads can be okay or absolutely treacherous - highly unpredictable. It is not uncommon for the highways to be closed due to extreme snow and or ice conditions.

According to my Rand McNally road atlas, Toronto to Vancouver is 4537 km (which is 2820 miles).

If you are driving the Trans Canada highway number 1, some of the way is four lane divided (or even six lane divided near the larger cities), but a lot of the way is two lane undivided as well (especially through northern Ontario, parts of Saskatchewan, and through the Rocky Mountains in B.C.).

Weather conditions are highly unpredictable in December - it could be dry and clear driving, or you could hit a blizzard (or even worse, freezing rain and sleet).
The other factor to consider is that in December the days are short, sun rises late and sets early, so you only have 6 to 8 hours of optimal driving conditions (best visibility) per day.
So plan at least five days for the drive, I would suggest that seven days is more realistic, and build in extra days into your plans, a day or two, just in case the weather is so bad you have to stop somewhere along the way.

The good news is that in December accommodation will be relatively easy to find (unless you plan on driving during Christmas week near ski areas).

Good luck!!

the length of your drive will depend on the weather and how many hours a day you drive. i have made this trip several time, most recently in jul05. because you are travelling in dec. take hwy 11 in ontario. it is not as scenic but it is a little safer. keep an eye out for wildlife on the roads esp. moose as they claim a few lives every year.
you could have clear highways or several inches of snow. you may want to factor in road closures due to winter storms/accidents.
in good weather toronto to thunder 13 hrs.
thunder bay to winnipeg 7hrs.
winnipeg to regina 6 hrs
regina to calgary 7-8 hrs
calgary to vancouver 11 hrs
good luck and be careful

If you just need to get a car from Toronto to Vancouver, or do it fast, then drive through the US. Faster, all freeway travel.

Winter tires are better than all-season on snow or ice, but they're usually softer - so they won't handle as well on dry pavement and they'll wear out much faster, especially if the temperature is high.

I drove a car from Rhode Island to Seattle once around Christmas, and took me 3.5 days, mostly on I-90. Toronto isn't even as far. I timed it perfectly so avoided a snowstorm in the plain states. Traffic is very light on I-90 once past Chicago, so I was doing about 85mph.

from toronto, it is faster to cut through the states. you can always head north into canada south of manitoba or saskatchewan.
do you have a block heater in your car? chances are you may not need it but depending upon how in shape your vehicle is, you may want to plug in if it gets below -20.
i wouldn't hesitate doing the trip. just build in extra time so if you get stuck somewhere while they clear the roads, it won't be a problem. if you've never been to the rockie mountains before, you should plan on staying a couple of nights.
