Quick answer
Mandamus is a Federal Court order compelling IRCC to decide an application it has left unreasonably delayed. It does not force IRCC to approve your file. Mississauga work permit, study permit and permanent residence applications stall most often in security screening. We act across Mississauga from our North York office.
What does a writ of mandamus do about an IRCC delay?
A writ of mandamus is an order from the Federal Court requiring IRCC to decide your application. It compels a decision, not a particular decision. It can end a delay of years, but it cannot turn a refusal into an approval.
The basis is s. 18.1 of the Federal Courts Act; immigration matters reach the Court under s. 72 IRPA. Our writ of mandamus in Canada page sets out the remedy.
Why do Mississauga applications get stuck at IRCC?
Security screening is the most common cause of a multi-year delay, and it catches applicants with extensive travel or work history abroad. Admissibility under A11.2, criminal or medical inadmissibility, and misplaced files account for the rest.
The mix follows the local economy. Near Toronto Pearson International Airport, Malton and the Airport Corporate Centre we frequently see delayed employer-linked work permits. In the Meadowvale business parks and along the Hurontario corridor near Square One, transfer and permanent residence files sit in processing. Students at the University of Toronto Mississauga in Erindale and Sheridan College’s Hazel McCallion Campus bring study permit and post-graduation work permit delays. From Streetsville, Cooksville and Erin Mills we frequently see spousal applications that went quiet after the medicals expired.
What do you have to prove to obtain mandamus?
The governing test is the eight-part test set out in Apotex Inc. v Canada (Attorney General), [1994] 1 FC 742 (FCA). In practice a Mississauga file has to show:
- A public legal duty to act, owed to you.
- A clear right to performance: every condition precedent satisfied.
- A prior demand for a decision, and reasonable time to comply.
- Refusal or failure to act within that time.
- No other adequate remedy.
- A balance of convenience favouring the order.
Unreasonable delay is measured against Conille v Canada (MCI), [1999] 2 FC 33: the delay is longer than the process requires, you did not cause it, and IRCC has no satisfactory justification. Exceeding a published IRCC processing time is evidence of delay, not proof.
How long does a mandamus application take?
Most files never reach a hearing, because IRCC finalises the decision once litigation starts. The sequence below is typical, never guaranteed:
| Stage | What happens | Typical timing |
|---|---|---|
| Demand letter | A written demand that IRCC decide | Allow roughly 30 days to respond |
| Filing | Application for Leave and for Judicial Review, Form IR-1 | Once the demand goes unanswered |
| Records | IRCC serves the certified tribunal record | Applicant’s record within 30 days of the leave application |
| Leave, then hearing | A judge decides leave on the written record; most files settle before this point | Leave typically a few months; hearing later |
One deadline point matters. Where a decision exists, s. 72(2)(b) IRPA allows 15 days to apply if the matter arose in Canada and 60 days if abroad. In a pure delay case there is no decision date to run the clock from, so counsel usually files once a demand letter has gone unanswered. See how to file a mandamus application.
Is mandamus the right remedy, or is it judicial review?
It turns on one question: has IRCC decided? No decision means mandamus. A decision you disagree with means judicial review, or an appeal if appeal rights exist.
| Mandamus | Judicial review | IAD appeal | |
|---|---|---|---|
| Trigger | No decision, unreasonable delay | A decision said to be unreasonable | A refusal carrying appeal rights, s. 63 IRPA |
| Forum | Federal Court, 180 Queen Street West | Federal Court | Immigration Appeal Division, 74 Victoria Street |
| Remedy | An order to decide | Decision quashed, sent back to another officer | A fresh hearing, new evidence allowed |
Appeal rights are not universal. Under s. 64 IRPA a foreign national found inadmissible for serious criminality, meaning a sentence of 6 months or more, or for organised criminality, security, or human or international rights violations, has no appeal to the IAD at all, and judicial review in the Federal Court is the only route left. Both Federal Court routes pass through the same leave gateway, and leave is granted in a minority of cases. Compare mandamus vs judicial review and mandamus vs IAD appeal, or ask an immigration mandamus lawyer in Toronto first.
Do you have to attend court in Toronto?
Rarely. The Federal Court hears immigration matters at 180 Queen Street West, but mandamus turns on the written record and most files settle first. We act for clients across Mississauga from our North York office at 1110 Finch Ave W #406, and most steps are handled remotely.
Mississauga is among the most linguistically diverse cities in Canada, and our team takes instructions in English, Russian, Farsi, Arabic, Portuguese and Spanish. Refused files, not delayed ones, are covered on our Immigration Appeal Division appeals page. The same work runs elsewhere in the GTA, from an immigration mandamus lawyer in Richmond Hill to an immigration lawyer in downtown Toronto, and at our own base, the immigration lawyer in North York page.

Frequently asked questions
Do you have an office in Mississauga?
No. Our only office is 1110 Finch Ave W #406, Toronto, ON M3J 3M2, in North York. We act across Mississauga from there, most steps handled remotely.
Do I have to travel to 180 Queen Street West?
Usually not. Mandamus is decided largely on the written record, and most files settle before a hearing, once IRCC finalises the decision.
Does mandamus force IRCC to approve my work permit?
No. Mandamus compels a decision on a delayed application. That decision may still be a refusal, challenged by judicial review or, where appeal rights exist, at the IAD.
My file has been in security screening for years. Is that enough?
It is the most common basis for a delay case, but not an automatic one. The delay must exceed what the process requires, you must not have caused it, and IRCC must have no justification for it.
My employer near Pearson applied for a work permit that is still pending after a year. Is that a mandamus case?
Possibly. Employer-linked work permit delays around Malton and the Airport Corporate Centre are among the files we frequently see. The Federal Court asks the same three questions in every delay case: is the delay longer than the nature of the process requires, did you contribute to it, and has IRCC given a satisfactory justification. A written demand that IRCC decide comes first, and a reasonable time to comply after that.
What does a mandamus application cost?
The Federal Court filing fee is modest. Legal fees are the larger part and vary with complexity and with how early the file settles. Ask for a written quote.
