Judicial Review of Visa Refusals: The UK and Canada Compared

For the internationally-mobile applicant, a visa refusal in the United Kingdom and one in Canada raise the same instinctive question — can this be challenged? — but the answer, and the machinery behind it, differs in ways that matter enormously in practice. Both countries offer judicial review: a court examining the lawfulness of an immigration decision rather than re-deciding it on the merits. Yet the deadlines, the forums, the procedural steps and the strategic calculus are far from identical, and an applicant who assumes the two systems work the same way can lose a remedy simply by importing the wrong assumption.

This briefing sets the two side by side. It is written for those who deal with refusals across jurisdictions — and as a companion to our separate, detailed guides on judicial review of UK visit visa refusals and of Canadian visa refusals, to which readers should turn for the full treatment of each. A necessary note: both the UK and Canada are outside our jurisdiction of admission. This is general information only; anyone facing a refusal should take advice from a lawyer or authorised adviser in the relevant country, and promptly, because in both systems the time limits are short.

The shared foundation

Before the differences, the common ground — because it is the part applicants most often misunderstand, identically, in both countries.

In both the UK and Canada, judicial review is not an appeal. Neither court asks whether the visa officer reached the right decision or re-weighs the evidence. Both ask only whether the decision was made lawfully — whether it was unreasonable, procedurally unfair, or affected by an error of law. In both systems, judicial review admits no new evidence: the court examines the decision on the record that was before the officer. And in both, a successful challenge does not produce a visa — it quashes the unlawful decision and returns the matter for a fresh, lawful reconsideration by a different decision-maker, who could, in principle, refuse again. In both countries, the remedy is a lawful re-decision, not an approval. And in both, there is a permission filter: no applicant is entitled to a full hearing without first persuading the court that the case is genuinely arguable.

Hold those shared features in mind. Almost everything that differs is procedural — but procedure, in this area, is decisive.

Difference one: the forum

In the UK, most immigration judicial reviews — including visit visa refusals — are brought in the Upper Tribunal (Immigration and Asylum Chamber), a specialist tribunal, rather than the ordinary courts. Certain categories (a refusal of British citizenship, for example) must instead go to the Administrative Court, so identifying the correct forum is itself a preliminary question.

In Canada, immigration judicial reviews are brought in the Federal Court of Canada — a single national court with jurisdiction over federal decision-making, including the decisions of IRCC.

The practical significance is that each is a specialist forum with its own rules, its own forms and its own culture, and neither is the general civil court an applicant might expect. In both, expert local representation is effectively essential.

Difference two: the deadlines — and this is where remedies are lost

This is the single most important divergence, and the one most likely to catch out an applicant reasoning by analogy.

In the UK, a judicial review claim must be brought promptly, and in any event within three months of the decision. "Promptly" can in principle be shorter than three months, but three months is the outer limit.

In Canada, the deadline is dramatically shorter and depends on where the decision was made: 15 days if the decision was made inside Canada, and 60 days if it was made outside Canada. For the typical overseas applicant refused at a visa office abroad, the window is 60 days — but a subtle and dangerous point applies: the deadline turns on where the officer was, not where the applicant was. A decision made by an officer inside Canada carries the 15-day deadline even if the applicant was overseas.

The contrast is stark. An applicant who carries a UK-shaped assumption of "three months" into a Canadian refusal can miss the Canadian deadline before they have even taken advice. In both systems the clock runs from the date the decision is received — not from when the applicant decides to act, and not from when they obtain the officer's reasons.

Difference three: how you get the officer's reasons

In both countries, the refusal letter is thin, and the real reasoning lies in the officer's internal notes — but the mechanism for obtaining them differs, and this shapes the sequence of steps.

In the UK, the detailed reasoning is typically sought before issuing proceedings, and the process is front-loaded by a mandatory pre-action step (below). The applicant assesses the decision, then challenges it.

In Canada, the sequence is reversed in a way newcomers find counter-intuitive. The applicant must file the Application for Leave and for Judicial Review (ALJR) first — within that tight 15/60-day window — often before seeing the officer's full reasons. Only after the ALJR is filed does the Federal Court request the officer's notes from IRCC under what is known as Rule 9. The "Rule 9 reasons" are the equivalent of the officer's internal record, and they arrive after the claim has been commenced. In practice, this means a Canadian applicant frequently must decide to litigate, and file, on limited information — and then perfect the argument once the reasons are disclosed.

This structural difference has a real consequence: the Canadian system compresses the initial decision-to-file window severely, because filing comes before full disclosure. The UK system allows more of the assessment to happen before the formal claim.

Difference four: the pre-action step

In the UK, there is a mandatory Pre-Action Protocol (PAP). Before issuing a claim, the applicant must send a formal letter to the Home Office setting out why the decision is unlawful and inviting reconsideration. This step matters enormously in practice: a significant share of UK visa judicial reviews — figures around 30% are commonly cited — settle at this stage, with the Home Office conceding an obvious error, delivering the practical outcome without litigation. Critically, sending the PAP letter does not pause the three-month clock.

In Canada, there is no equivalent mandatory pre-action protocol. The process begins with filing the ALJR in the Federal Court. Settlement can and does occur — the Department of Justice may agree to send a matter back for redetermination once it assesses the perfected application — but it happens within the litigation, after filing, rather than through a required pre-action exchange beforehand.

The upshot: the UK builds in a formal, often decisive, off-ramp before court; Canada's equivalent resolution, where it happens, occurs after the claim is filed.

Difference five: the timetable after filing

Both systems run in two stages — permission (leave), then a substantive hearing if permission is granted — but the rhythm differs.

In Canada, after the ALJR is filed and the Rule 9 reasons received, the applicant must "perfect" the application by filing the complete record and argument. A recent and important change, effective 14 May 2025, extended the perfecting period from 30 days to 75 days — a meaningful easing that gives applicants more time to assemble the full case (the initial 15/60-day filing deadlines were unchanged). A judge then decides leave on the papers, usually without a hearing; if leave is refused, the matter ends, with no appeal from a refusal of leave. If leave is granted, a hearing is generally held within a defined window — commonly cited as 30 to 90 days — at which oral submissions are made and no new evidence is introduced.

In the UK, after the claim is issued, the Home Office files an Acknowledgement of Service, a judge decides permission on the papers (with a limited ability to renew if refused), and, if permission is granted, the matter proceeds to a substantive hearing — the whole process commonly running several months to well over a year amid tribunal backlogs.

In both, the overall timeframe is measured in many months, and in both, appealing onward from the judicial review is tightly constrained — in Canada, notably, only where the judge certifies a serious question of general importance.

What is the same, strategically

Beneath the procedural contrasts, the strategic logic is strikingly similar in both countries, and worth stating plainly because it governs the threshold decision in each.

In both the UK and Canada, judicial review is the right route only where the decision was genuinely legally defective — unreasonable or unfair — rather than merely unfavourable on a weak application. In both, the better route for a fixable refusal (thin evidence, a missing document, an unpersuasive account) is usually to reapply, because both systems permit reapplication, both decide fresh applications far faster than litigation, and both allow the new evidence that judicial review forbids. And in both, a refusal containing a serious adverse finding — particularly an allegation of misrepresentation or deception, which can carry multi-year bans in each country — may need to be challenged rather than left to contaminate future applications. The distinguishing question, in both systems, is not how sympathetic the applicant is, but whether the decision was lawful.

The comparison at a glance

• Nature of remedy: Both — reviews lawfulness, not merits; no new evidence; a win means reconsideration, not a visa.

• Forum: UK — Upper Tribunal (IAC), usually. Canada — Federal Court.

• Deadline: UK — promptly, within 3 months. Canada — 15 days (decision made in Canada) or 60 days (made outside).

• Getting the officer's reasons: UK — generally before filing. Canada — after filing, via Rule 9.

• Mandatory pre-action step: UK — yes (Pre-Action Protocol; ~30% settle). Canada — no.

• Permission stage: Both — leave required; decided on the papers; no full hearing as of right.

• After a win: Both — remitted for fresh decision by a different officer.

• Onward appeal: Both tightly restricted (Canada — only on a certified serious question of general importance).

A concluding observation

Judicial review exists in both the United Kingdom and Canada as a genuine safeguard against unlawful immigration decisions, and the deep principles are shared: it tests legality rather than merit, admits no new evidence, and delivers a lawful reconsideration rather than a visa. But the machinery diverges in ways that decide real cases — above all the deadlines, where Canada's 15-or-60-day window is a fraction of the UK's three months, and the sequence, where Canada requires filing before the reasons are disclosed while the UK front-loads a decisive pre-action exchange. For anyone operating across these jurisdictions, the lesson is that the remedy cannot be understood generically. The right court, the right deadline and the right sequence are specific to each system — and getting them wrong in one because they differ in the other is precisely how a valid challenge is lost before it begins.

It is published for general information and awareness only, does not constitute legal advice, and no professional engagement is offered or implied. Immigration litigation in both countries is highly technical and time-sensitive, time limits are strict and differ between and within jurisdictions, and rules and case law change.
