When a tax dispute is large, legally complex, or important enough to warrant full litigation, it proceeds in the Tax Court of Canada under the General Procedure. This is the Court's complete civil-litigation track — formal pleadings, documentary and oral discovery, undertakings, expert evidence, and a trial conducted under the rules of evidence, with costs consequences for the losing side. This guide walks through each stage of a General Procedure appeal, explains the pieces that surprise taxpayers most, and sets out when the General Procedure applies rather than the simpler Informal Procedure.
When the General Procedure applies
The General Procedure applies to every Tax Court appeal that is not conducted under the Informal Procedure. In practice that means:
- appeals where the federal tax in dispute for a year exceeds $25,000 (or the GST/HST amount exceeds $12,000, or the loss exceeds $50,000), and the taxpayer has not elected to surrender the overage; and
- any appeal where the taxpayer chooses the General Procedure, regardless of the amount — for instance, because the case turns on a point of law where a binding precedent or a full right of appeal is wanted.
The thresholds and the Informal alternative are set out in The Tax Court Informal Procedure, Explained. A corporation generally must be represented by counsel in the General Procedure; an individual may self-represent, though the formality of the process makes representation valuable.
Stage 1 — pleadings
A General Procedure appeal is built on formal pleadings that define the boundaries of the dispute.
The notice of appeal
The appeal begins with a notice of appeal that states the material facts, identifies the issues, cites the statutory provisions relied on, and sets out the relief sought. It must be filed within 90 days of the notice of confirmation (or after the 90-day no-decision threshold). Unlike the Informal Procedure, the General Procedure notice of appeal is held to formal drafting standards, because the Crown's reply will engage on its framing. The filing mechanics are covered in How to File a Notice of Appeal.
The reply
Department of Justice counsel, acting for the Minister of National Revenue, file a reply. The reply admits or denies the facts pleaded, states the Crown's position, identifies the statutory basis for the reassessment, and — most importantly — sets out the assumptions of fact the Minister relied on at the reassessment stage. Those assumptions matter enormously, because the taxpayer carries the burden of rebutting them. Why that burden falls where it does is explained in Evidence and Burden of Proof in Tax Court.
The answer
The taxpayer may file an answer to respond to new matters raised in the reply. The answer is optional and is used where the reply pleads facts or positions that call for a response.
Stage 2 — documentary discovery
After pleadings close, the parties exchange lists of documents. Each side discloses the documents relevant to the matters in issue that are or were in its possession or control. There are two forms of disclosure in the General Procedure — a partial list and a full list — and the Court can order the more comprehensive form. Documentary discovery is where the evidentiary foundation of the case is laid bare. The taxpayer's own records drive the appeal; the scope of what the Crown must look for is shaped by the assumptions of fact it pleaded.
Stage 3 — examinations for discovery
The General Procedure includes oral examinations for discovery. Each party may examine one representative of the other side, under oath, before a court reporter, in advance of trial. Discovery serves several purposes: to learn the other side's case, to obtain admissions, to test the strength of the assumptions, and to pin down positions so there are no surprises at trial. Many appeals are effectively won or lost at discovery, because it is where the Crown's theory is probed and where the taxpayer's account is tested before a judge ever hears it.
Stage 4 — undertakings
During an examination for discovery, a witness will frequently be asked to provide a document or a piece of information that is not available in the room. The commitment to provide it afterward is an undertaking. Undertakings are a routine and important part of the General Procedure: the answers and documents provided in satisfaction of undertakings become part of the discovery record, and a failure to honour an undertaking can have consequences, including a refusal to allow the withheld evidence at trial. Tracking, answering, and following up on undertakings is a meaningful part of the work between discovery and trial.
Stage 5 — expert evidence
Some appeals require an expert report — a business valuation, an accounting reconstruction, a transfer-pricing analysis, an industry-practice opinion. Expert evidence is governed by the Court's rules: the witness must be qualified, the report must be served in advance, and the expert witness may be cross-examined at trial. A well-prepared expert opinion can be decisive on a technical issue a judge is not otherwise equipped to resolve, and the rules around the timing and exchange of expert reports are strict, so expert evidence is planned early rather than late.
Stage 6 — settlement
Most General Procedure appeals settle before trial, frequently after discovery, when both sides can see the strengths and weaknesses of the case. Settlement in tax litigation is permitted only on a principled basis — a result the law and the facts could actually support — not by simply splitting the difference. How that constraint works, and when settlement is and is not possible, is the subject of Settling a Tax Court Appeal Before Trial.
Stage 7 — trial
If the case does not settle, it proceeds to trial: live witness testimony, documentary evidence, any expert evidence, cross-examination, and legal argument, all under the formal rules of evidence. Many taxpayer trials run from one to five days, though complex cases run longer. What the trial day itself involves is described in What to Expect at a Tax Court Hearing.
Stage 8 — judgment and costs
The Court issues reasons and a formal judgment. The reassessment may be upheld, vacated, or — most commonly when the taxpayer succeeds in part — referred back to the Minister for reconsideration and reassessment in accordance with the reasons. Costs are a real feature of the General Procedure: the successful party can be awarded costs against the other, calculated on the Court's tariff or, in appropriate cases, on a more substantial basis. That cuts both ways — a recovery if you win, an exposure if you lose — and it has to be factored into strategy, including the assessment of any settlement offer.
Further appeals
A General Procedure judgment can be appealed to the Federal Court of Appeal, generally within 30 days, on a question of law or a palpable and overriding error of fact. A further appeal to the Supreme Court of Canada requires leave and is granted only in cases of broad significance. This full right of appeal is one reason a taxpayer may choose the General Procedure even where the Informal Procedure is available.
How we help
Barrett Tax Law conducts General Procedure appeals from the notice of appeal and pleadings through documentary and oral discovery, undertakings, expert evidence, settlement discussions, and trial. Because the assumptions of fact pleaded in the reply define the taxpayer's burden, the case theory is built around them from the outset.
