A criminal record is where most refusals start. Serious criminality catches a conviction for anything carrying a maximum of ten years or more, or any sentence longer than six months, and it reaches permanent residents too. Ordinary criminality catches foreign nationals for an indictable offence, or two separate offences, in Canada or abroad. Even an act you were never charged with can count if it would be an offence here.
(2)A foreign national is inadmissible on grounds of criminality for (a)having been convicted in Canada of an offence under an Act of Parliament punishable by way of indictment, or of two offences under any Act of Parliament not arising out of a single occurrence; (b)having been convicted outside Canada of an offence that, if committed in Canada, would constitute an indictable offence under an Act of Parliament, or of two offences not arising out of a single occurrence that, if committed in Canada, would constitute offences under an Act of Parliament; or (c)committing an act outside Canada that is an offence in the place where it was committed and that, if committed in Canada, would constitute an indictable offence under an Act of Parliament. (d)[Repealed, 2023, c. 32, s. 53]
(2.1)A foreign national is inadmissible on grounds of transborder criminality for committing, on entering Canada, a prescribed offence under an Act of Parliament.
