Do I need of BSN to work in Canada?

Canada doesn't have states, we have provinces. Each province sets their own requirements for registration, but the BScN is an absolute requirement for entry to practice in all provinces but Quebec, which has its own educational system. You can apply for registration in any province you want, but be aware that Canadian registrations cost considerably more than those in the US, are good for only one year at a time and holding several registrations will be horrendously expensive. You don't need to have a job to apply; the colleges of registered nurses don't care if you have a job or not until it's time to renew your registration. However, you will have to meet minimum requirements for licensure before your application will be approved; you'll have to pass the Canadian Registered Nurse Examination as well. Have a look at some of the colleges' websites and read about those requirements before you make any decisions. https://allnurses.com/canadian-nurses/links-provincial-colleges-303171.html

This thread will now move to the International Forum.

No there aren't. Not really. At times, when there are lots of vacant jobs across the country and there aren't enough newly graduated Canadian nurses available to fill them, hospitals and regional health authorities will recruit internationally, but that isn't the case these days. There are many Canadian nurses who aren't finding jobs at all so the odds of getting a favourable LMO at all are very slim.
