Yes, I got into NSU-COM. You can get the information from the AOA or the province you are concerned about (but I'll save you the trouble).
Alberta: Scope of practice: unlimited
Requirements: must write and pass all three parts of the MCC (Medical Council of Canada) exams, two years of ACGME-accredited graduate medical education
British Columbia: Scope of practice: Two pathways (one for unlimited rights and another for DO's who just want to practice manipulation)
requirements: one year GME that is AOA or ACGME accredited and one year of GME in Canada, and all three parts of MCC exams (for only OMM just complete an AOA residency)
Manitoba: No provisions exist, must petition licensing authority
New Brunswick: Scope: unlimited
Requirements: AOA or ACGME-accredited residency, and all three parts of the MCC
Newfoundland: no provisions exist, must petition lic. auth.
Northwest Territories: no provisions, must petition
Nova Scotia: no provisions, must petition
Ontario: scope: limited to OMM (there is a moratorium placed on issuing licenses that applies to both DOs and MDs). MDs trained outside Ontario can't get licenses either.
Saskatchewan: scope: limited to OMM
Yukon Territory: no provisions, must petition
I hope that helped. Personally, I'm from Alberta so if I did want to return it would not be difficult. Also, petitioning is getting easier and easier for US-trained DOs. Another point... the other provinces are coming around (I was told by people at the Canadian Osteopathic Association that by the time I graduated it would be a non-issue). I hope they are right, but it doesn't really matter to me as I like Alberta and have claim to US citizenship.
