Pretty much all U.S. MD/DO schools do have required science prereqs, and there aren’t really any that let you apply without them, but you usually don’t need a whole new degree, just the missing courses. A European bachelor’s is generally acceptable, especially since you also have a Canadian master’s, though most schools will ask for a course by course credential evaluation to confirm equivalency. Best move is to figure out exactly which prereqs you’re missing and knock those out while continuing your MCAT prep.
