Wrong... Not just felony but Misdemeanor also. I've seen first hand. This is taken from The Canadian Immigration site. Google misdemeanor and Canada entry, if you still think It's just felonies that you will have issues with.

otherwise, even a single alcohol related driving conviction such as DWI, DUI, DWAI, OVI, or OWI can render you excluded from Canada. Even drunk driving plead down to a wet reckless driving or careless driving charge can result in a denial of entry at the border.


Other misdemeanor convictions that can get you barred from crossing the border include assault, burglary, resisting arrest, possession of a controlled substance, theft, and unlawful possession of a weapon.
