Re: Driving Edmonton to Montreal Take the 11, it's flatter and less hilly so better on gas, and 30mins shorter than the 17 to boot.
Secret: There's a reserve gas station right past where the 11 splits from the 17, on the right. No tax on that gas. Fill up there.
When you hit North Bay, take the 17 east, it's way faster than going all the way south to the 401. It turns into the 417 once you hit Ottawa.
Source: I've done this drive a million times.
I've never found the 11 route to be quicker, myself... Can't disagree with the 'flatter' - 17's up and down a fair bit in spots.
