Quick answer

Canadian immigration litigation challenges an IRCC decision, or the absence of one, before the Federal Court or the Immigration Appeal Division. If IRCC has not decided your application, the remedy is a writ of mandamus. If IRCC refused it, the remedy is judicial review, or an Immigration Appeal Division (IAD) appeal where a right of appeal exists.

When do you need a writ of mandamus?

When IRCC has left your application undecided for longer than the process reasonably requires. Mandamus is a Federal Court order compelling IRCC to make a decision; it does not force an approval. You must show a public legal duty to decide, that every condition on your side is met, a prior written demand that went unanswered, unreasonable delay, and no other adequate remedy — the test in Apotex Inc. v Canada (AG), with delay measured under Conille. Read the full writ of mandamus in Canada guide.

When do you appeal to the Immigration Appeal Division (IAD)?

When you hold a statutory right of appeal under section 63 of IRPA. The IAD hears three kinds of case, and the hearing is de novo — new evidence is allowed:

  • Sponsorship appeals — a refused family-class sponsorship, appealed within 30 days of the written refusal.
  • Removal order appeals — by permanent residents, protected persons and permanent resident visa holders.
  • Residency obligation appeals — where a permanent resident is found short of the 730-days-in-5-years rule, with 60 days to appeal from abroad.

Our Immigration Appeal Division appeals guide sets out the process, and section 67(1)(c) of IRPA allows humanitarian and compassionate relief, including the best interests of a child.

The forums are compared in detail in mandamus vs judicial review and mandamus vs IAD appeal. Note that section 64 of IRPA removes the IAD appeal right for serious criminality (a sentence of six months or more), organised criminality, security, or human or international rights violations — those cases go to the Federal Court by judicial review instead.

Frequently asked questions

Does a writ of mandamus force IRCC to approve my application?

No. Mandamus forces IRCC to make a decision, not a favourable one. A refusal that follows is challenged separately by judicial review, or by an IAD appeal where appeal rights exist.

How long do I have to appeal a refusal to the Immigration Appeal Division?

30 days from receiving the written decision for a sponsorship or removal order appeal, and 60 days for a residency obligation appeal made from outside Canada.

What is the difference between judicial review and an IAD appeal?

Judicial review is decided on the officer's record and asks whether the decision was reasonable; the Court can only quash it and send it back. An IAD appeal is a fresh hearing where new evidence is allowed and humanitarian relief is available.

Is there ever no right of appeal to the IAD?

Yes. Section 64 of IRPA removes the appeal right for serious criminality, organised criminality, security, and human or international rights violations. Those cases proceed by judicial review in the Federal Court.
