MBBS degree validity

Hello everyone. I need help. Me amd my husband are doctors in india. We have done MBBS. We are planning to move to Canada . But before that i want some information regarding opportunities for an indian doctor. And what if we do diploma nursing there(with part time job). Do they consider MBBS credit to get admission in nursing.? My age is 29 and my husband’s age is 30 . Is it really worthy to move there and start from zero. I don’t my 5.5 years of hard work go in vain. What should we do?
