Federal Court Judicial Review of CRA Decisions in Canada: Costs and Timelines

17 Jun 2026 4 min read No comments CRA Tax Disputes & Audits Canada
💡

If the Canada Revenue Agency (CRA) denies a discretionary request, such as Taxpayer Relief to cancel penalties and interest, you cannot appeal to the Tax Court. Instead, you must file an Application for Judicial Review at the Federal Court of Canada. The strict filing deadline is 30 days, and the court fee is $50 CAD.

When Canadians think of fighting the Canada Revenue Agency (CRA), they usually picture arguing about tax brackets or denied business expenses at the Tax Court of Canada. However, the CRA makes many decisions that have nothing to do with calculating your exact tax bill. These are “discretionary decisions,” such as refusing to cancel massive interest charges under the Taxpayer Relief Provisions, denying the Canada Child Benefit (CCB) based on residency, or refusing to accept a late-filed Notice of Objection.

When the CRA makes an unfair or unreasonable discretionary decision, the Tax Court cannot help you. You must take your fight to the Federal Court of Canada. Whether you reside in Vancouver, British Columbia, or Toronto, Ontario, the Federal Court has the power to review the CRA’s actions and force them to reconsider your case. Because the legal threshold for proving an administrative error is extremely technical, retaining a skilled Canadian tax lawyer from our directory is the best way to present a winning argument.

Step-by-Step Process for a Judicial Review in Canada

Judicial Review is not a second chance to re-argue the facts of your taxes. The Federal Court judge is only looking at whether the CRA’s decision-making process was legally fair, reasonable, and unbiased. Here is how the process unfolds across Canada.

Step 1: Exhaust Internal CRA Avenues

Before you can apply to the Federal Court, you must use all the internal review levels the CRA offers. 🔍 For example, in a Taxpayer Relief case, you must complete both the First Level and Second Level reviews. If the Second Level decision from the CRA director is a denial, you now have a “final” administrative decision that is eligible for Judicial Review.

Step 2: File the Notice of Application

You have a remarkably strict deadline: you must file your Notice of Application with the Federal Court within exactly 30 days of receiving the CRA’s final decision letter. Missing this deadline is often fatal to your case. Your law firm will draft this legal document outlining exactly how the CRA breached procedural fairness or made an unreasonable decision based on the evidence before them.

Step 3: Receive the CRA’s Tribunal Record

Once you file, the Department of Justice (the lawyers representing the CRA) must produce the “Tribunal Record.” This is a complete copy of every document, note, and piece of evidence the CRA officer looked at when making their decision. You and your lawyer will review this package to find flaws in the CRA’s logic or instances where they ignored your vital evidence.

Step 4: Prepare Affidavits and Attend the Hearing

Judicial Review is typically a “paper-based” process. You generally cannot call live witnesses. 🗣 Instead, your lawyer will submit a sworn Affidavit and a written Memorandum of Fact and Law. You will then attend a hearing (often held in major cities like Calgary, Alberta, or Ottawa, Ontario) where your lawyer and the Crown lawyer present oral arguments to the Federal Court judge.

How Much Does it Cost in Canada?

Pursuing a Judicial Review at the Federal Court is a formal legal undertaking that involves specific costs. All estimated amounts are in Canadian dollars (CAD).

  • Federal Court Filing Fee: $50 CAD for the Notice of Application.
  • Lawyer Fees: Retaining a specialized tax law firm typically costs between $7,500 and $20,000 CAD, depending on the volume of the CRA record and the complexity of the arguments.
  • Court Costs: If you win, the judge may order the CRA to pay a portion of your legal fees. If you lose, you may be ordered to pay a portion of the government’s legal costs.

How Long Does the Process Take?

📅 After filing within your strict 30-day window, the procedural steps (exchanging records, cross-examining affidavits, and filing memorandums) take several months. Generally, a Judicial Review at the Federal Court takes between 9 to 14 months from the date of filing to the day you receive the judge’s final written decision.

Frequently Asked Questions (FAQ)

Can I submit new evidence to the Federal Court?

Generally, no. The Federal Court’s job is to review the decision based strictly on the information the CRA officer had at the time. You cannot introduce new financial documents that you forgot to give the CRA earlier.

What happens if I win the Judicial Review?

If the judge sides with you, they do not usually grant your Taxpayer Relief themselves. Instead, they “quash” (cancel) the CRA’s refusal and order the CRA to review your file again with a new, unbiased officer, following the judge’s instructions.

Does filing for Judicial Review stop CRA collections?

No. Unlike appealing a tax assessment to the Tax Court, applying for Judicial Review at the Federal Court does not automatically pause CRA collection actions. You may need to negotiate a payment arrangement with CRA Collections while your case proceeds.

Do I absolutely need a lawyer for the Federal Court?

While individuals can self-represent, corporate entities must be represented by a lawyer. Administrative law is incredibly complex, and arguing a “standard of review” without a specialized Canadian tax lawyer is exceptionally difficult.
