Not sure where you would look for a good gig in Canada regarding emigration nowadays. I have been here a long time and it’s been a while since I had to go through the process myself but I will say that if you want real long haul then here in Manitoba would be a good choice regarding which province to choose I reckon.
Always seems that most of the fellow Canadians I encounter in the furthest away from home States are from either from Manitoba or Alberta and to a smaller degree BC and Ontario also.
Another thing to consider is the fact that the real good to work for type of companies don’t generally need to recruit from halfway round the world in order to get drivers and the ones that do, well, I am sure you can work that part out.
