I have friends that live in Fort Mac. They said Cost of living is extremely high. Because this is where all the rig people live.(Oil and Gas) And they make a lot of money thus everything else is expensive. For example in the City (Edmonton or Calgary) a person that works in a fast food chain makes 9-11.50 dollars for a normal employee, compared to same job in Fort Mac that makes 17-21 dollars. Just so they even have a chance to survive. Apparently 3000 dollars a month for a 3 bedroom house is the rental. I know Rig workers that actually make 80-100/hour. So Prices like these aren't a problem with them.
I don't know if these are actual truth or they were just bragging but these were just information passed on to me.
Goodluck!
Oh PS. A lot of accommodations or rentals are paid by employers who sent in workers from the City thus making the rental market higher than normal.
