Does a criminal conviction in Canada take away my right to appeal to the Immigration Appeal Division?

It can, but not automatically for every conviction. The right to appeal a removal order to the Immigration Appeal Division (IAD) is removed for people found inadmissible on certain serious grounds, which typically depend on the length of the sentence imposed or the specific type of offence involved, rather than the mere existence of a criminal record. A minor conviction that does not meet these thresholds generally does not remove IAD appeal rights on its own.

Where the loss of appeal rights does apply, it is a complete bar on the IAD hearing the case at all — not just a harder appeal, but no jurisdiction for the IAD to consider the removal order on its merits or on humanitarian and compassionate grounds. In that situation, the only remaining route is judicial review at the Federal Court, which is a narrower legal review, not a fresh look at the facts or an assessment of hardship.

Because the exact thresholds matter a great deal here, and because IRB and CBSA characterizations of a conviction can be contested, anyone facing a removal order with a criminal record should get the specific inadmissibility finding reviewed rather than assuming either outcome.
