No incentive here. You do get a rural northern allowance if you go up north but not where you will be going... We don't get paid a whole lot to stay or what not.. but overtime for full time staff starts at double time. For casuals, rules for OT are quite strict and different than regular staff (has to be five 12 hour shifts in a row etc... ) so I did pick up more than full time hours but never got it paid as OT as a casual due to the strict rules. (read the collective agreement for more info).
Canadian nurses in BC (full timers) do work a lot more than nurses in the state or other province. General full time schedule is 2 days-2nights and 4 days off (days off start from the end of your night shift), rinse and repeat with some variation of 1 day-3nights or 3 days-1 nights. It might be easy for you to adjust because you work 4-12's anyway. It is however, quite hard to get days off without swapping with somebody. (since vacations all have to be pre-picked for the entire next year before that year.. ex Oct-Nov 2018 is when we choose all our vacation for entire year of 2019) My husband is American and I immigrated to Canada before we got married. He likes living in Canada and we are planning on moving more rural which is why he has to change his license but he is not prepared to work so many hours up here haha.
Regarding your experience, if you get hired in acute care or a similar field your experience will get accepted and your wage will be higher than a new grad for sure. However, your seniority will start from 0 hours. As a casual you will have to pick up quite a few random shifts on short notice to rack up seniority hours. After about 1000 hours or less, you can pick up rotations, blocks, vacation coverages and etc and have a comfortable schedule.
