If you are asking how long the days are, they are 14 hours, and if you are in a utility job, when on contract you basically work every day (except weather days, which you consider as resting days) for up to 42 days straight. In the 42 day period you need 13 days of rest (weather days), and 5 days to reset.
I consider myself lucky, and work 28 on 28 off, but my days can get long and boring, I'm basically on for 14 hours, but I plan the days activity, go to my days location, sit there for most of the day in a noisy environment, and get back, just in time for duty days end.
Finding an "easy" job in Canada at this time, when guys are struggling to find even a little work is not really feasible in my opinion. But others have prevailed, so best of luck to you!
