Yes, Canada requires DOs to complete an ACGME-accredited residency if they hope to practice in Canada. However, a number of dually-accredited residency programs are available (both DO and MD) that have varying degrees of osteopathic influence and training with the backing of the ACGME. Most of these dually-accredited programs are in general practice, but some specialties also have some dually-accredited program. If you'd like a current list of programs who are DO/MD certified, I'm sure you can contact the AOA. Best of luck!
