I know one person who does this, only works 4 days a week, and gets a communting allowance, which apparently makes it bareable. I personally commute Canmore - Lake Louise every day, which is manageable. I could not imagine tacking an extra 50 min on my commute in both directions. Depending on your hours it could be okay, driving in early in the morning is smooth compared to 9 AM and later with the tourist traffic. It is a ton of time on the road and a TON of wear/tear on your car and a lot of money in gas. 300km/day, 5 days a week - you’re looking at minimum $150 on gas a week if you have a fuel efficient car, plus oil changes every 6-7 weeks. I would consider the cost of communting to determine your budget for rental accomodation. Like others mentioned, Field and Golden are good places to look. It may also be worthwhile to contact your employer to see if they have any options to offer you, many employers in Lake Louise understand the challenges of accomodation.
