Mandamus · Federal Court of Canada
When IRCC will not decide, a court can order it to.
An application that sits for years without an answer is not something you are required to accept. Mandamus is the Federal Court order that compels Immigration, Refugees and Citizenship Canada to make a decision on a file it has held for an unreasonable time. It does not decide the outcome. It ends the silence.

What mandamus is
An order to decide. Not an order to approve.
Web forms, status checks, and letters from a Member of Parliament are requests. IRCC can answer them with a template. Mandamus is different in kind: a judge of the Federal Court directs the department to perform its duty, and sets the date by which it must.
Binding, with a deadline
The order names a period within which IRCC has to decide the application. It is a judgment of the Court, not correspondence, and the department is bound by it.
About the delay only
The Court does not weigh whether you qualify. It examines how long the file has been held, who caused the wait, and whether the explanation offered is good enough.
Open to most application types
Permanent residence, sponsorship, citizenship, work and study permits, and visas. The remedy applies wherever the law requires an officer to reach a decision.
When delay is unreasonable
Slow is not enough. Unexplained is.
The Court uses a three-part test. The delay has to be longer than the nature of the process requires. The applicant and their representative must not be responsible for it. And the authority responsible must not have provided a satisfactory justification.
Each part is a question of evidence. A file that stalled because a document request went unanswered will fail the second part. A file held for security screening, with nothing said about why or for how much longer, often satisfies the third.
Tell us how long you have waitedFrom a stalled file to a decision
Establish what is holding the file
We obtain the officer's notes and assemble the full timeline: what was submitted, what IRCC asked for, what was answered, and every inquiry made since.
Make the formal demand
A lawyer's letter sets out the delay and gives IRCC a fixed period to decide. Some files move at this stage. If not, the letter becomes evidence that the duty was demanded and not performed.
File in Federal Court
An application for leave and for judicial review is filed, seeking mandamus. The Department of Justice is served and a government lawyer takes carriage of the file.
Decision, agreement, or hearing
IRCC may decide the application once litigation begins, or agree to a timeline. If it does neither, the matter is argued before a judge, who can order a decision by a set date.
What changed in 2026
The law on delay moved twice this year.
Guidance written before 2026 is out of date. One change came from the Federal Court of Appeal and favours applicants. The other came from Parliament and gives the government new tools. Both have to be considered before a mandamus application is filed.
Benison, March 2026
In 2026 FCA 53, the Federal Court of Appeal clarified the mandamus test. An applicant does not need to prove significant prejudice, does not need to disprove every discretionary objection in advance, and cannot be answered with backlogs and resource limits as a justification for open-ended delay.
Bill C-12, March 2026
The Strengthening Canada's Immigration System and Borders Act allows the government to suspend or end processing for groups of applications in the public interest. Where a lawful measure of that kind covers a file, the duty to decide it has to be examined in that light.
Why it's worth doing right
Filed too early, it fails. Filed carelessly, it backfires.
Mandamus is litigation against the Government of Canada, answered by lawyers from the Department of Justice. The strength of the case is set before it is filed: by the timeline, by the record of what was asked and answered, and by the condition of the application that IRCC will be ordered to decide.
Timing judged against the law
We compare your wait with posted processing times and with recent decisions on similar files, and tell you plainly if it is too soon.
A record with no gaps
Any delay traceable to the applicant weakens the case. We confirm every request was answered and every document is current before the Court sees the file.
The application itself, reviewed
An order produces a decision either way. We look for the weaknesses an officer would find and address them first where the law allows.
Representation in Federal Court
Licensed immigration consultants are not permitted to act in Federal Court proceedings. A lawyer prepares the application, the affidavit evidence, and the argument.
What an order looks like
90
days given to IRCC in an August 2026 decision
In Yao v. Canada (Citizenship and Immigration), the applicant had waited about four years and eight months for a decision on a permanent residence application. The Federal Court ordered the Minister to decide it within 90 days. Every case turns on its own facts, and a past result does not predict a future one.
Have your delay assessedCommon questions
What applicants ask us about mandamus.
What is mandamus in Canadian immigration law?
Mandamus is an order of the Federal Court of Canada that compels a government decision-maker to perform a legal duty it has failed to perform. In immigration and citizenship matters, it is used when Immigration, Refugees and Citizenship Canada (IRCC) has held an application for an unreasonable length of time without deciding it. The order directs IRCC to make a decision, usually by a date set by the Court.
Does a mandamus order mean my application will be approved?
No. Mandamus compels a decision, not a particular result. The Court does not assess whether your application should succeed, and the officer remains free to approve or refuse it according to the law. What the order ends is the waiting. If a refusal follows, it can be challenged separately by judicial review.
How long do I have to wait before applying for mandamus?
There is no fixed number of months. The Court asks whether the delay has been longer than the nature of the process requires, whether the applicant or their representative is responsible for it, and whether the government has given a satisfactory justification. IRCC's posted processing time for the application type is the usual starting benchmark. A delay well beyond it, with no explanation specific to the file, is where mandamus becomes realistic.
What do I have to prove to obtain mandamus?
The Federal Court applies the considerations set out in Apotex Inc. v. Canada (Attorney General). In Benison v. Canada, 2026 FCA 53, the Federal Court of Appeal explained that the first four establish the grounds: a public legal duty to act, owed to the applicant, a clear right to have it performed, including a prior demand and a reasonable time to comply, and unreasonable delay. The remaining considerations, such as whether another adequate remedy exists and where the balance of convenience lies, are discretionary reasons the Court may still decline the order if they are raised.
Can IRCC justify the delay by pointing to its backlog?
Not by that alone. In Benison, decided in March 2026, the Federal Court of Appeal held that backlogs and limited resources could not justify open-ended delay. The Court looks for an explanation tied to the individual file. A general statement that background checks are ongoing, with no detail, has often been found insufficient.
Do I have to show that the delay is harming me?
Significant prejudice is not a legal requirement. The Federal Court of Appeal confirmed this in 2026. Evidence of harm still matters, because it helps the Court weigh the balance of convenience, and it has to be proven, not asserted. Family separation, lost employment, expired medical exams, and children aging out of eligibility should be supported by documents and a sworn affidavit.
Will taking IRCC to court hurt my application?
It should not. An officer must decide an application on its merits and the law, and a decision made for any other reason could itself be set aside by the Court. What mandamus can do is bring forward a decision that was going to be negative anyway. For that reason the underlying application should be reviewed for weaknesses before anything is filed.
What should I try before going to Federal Court?
Order your file notes (known as GCMS notes) to see what is actually holding the application, use IRCC's web form, and ask your Member of Parliament's office to make an inquiry. If none of that produces movement, a formal demand letter from a lawyer gives IRCC a final, dated opportunity to decide. That letter is also part of the legal test: the Court expects to see a prior demand and a reasonable time to respond.
Did Bill C-12 change mandamus?
It can affect whether a duty to decide exists. The Strengthening Canada's Immigration System and Borders Act, in force since March 26, 2026, gives the government new powers to pause or end the processing of groups of applications in the public interest. Where such a measure lawfully applies to a file, the analysis changes. Most delayed applications are not subject to one, but it is now a question that has to be checked at the start.
