The basis of registration from one province to the next is that there is an agreement that each province accept the same registration exam, which is done at a national level. The competencies for midwives have been developed at a national level. There are some small additions that various jurisdictions have added to the requirement to get registered, but usually something can be accomplished in writing a small examination or attending a workshop to add in the additional either competencies or knowledge of how the registration or regulations work in that particular area.
It is possible to move from one province to another. They can do that right from graduation, but particularly once a midwife has one year of experience, then cross-province or into territories is not that difficult.
