When I moved here to Calgary I drove from Montreal, and it toke me about 3 days, I got here in town around 4 o'clock the 3rd day. I want to drive back this summer as well (In August) but I want to make it in 2 days. I know that to get to Montreal it's about 3700 KM. If you go an average of 100KM, it about 37 hours, but I never drive that slow.
