Key takeaways
  • The Crown must file its reply within 60 days after service of your notice of appeal in the general procedure, and within sixty days after transmission in the informal procedure.
  • A general procedure reply must set out, among other things, the facts admitted and denied and the issues to be decided, and the Crown's assumptions appear in it.
  • You may file an answer to the reply within thirty days after it is served in the general procedure.

Some weeks after you file your notice of appeal, a document arrives from the Crown. It is called the reply, and it is the CRA's side of the story. It often includes a list of assumptions the CRA made when it assessed you.

This article explains what the reply is, why the assumptions matter, and what you can do in response. It is general information, and it is wise to have a lawyer or accountant review the reply with you.

This article covers Canadian federal tax law, which applies in every province.

What the reply is

The reply is the Crown's formal response to your notice of appeal. In the general procedure the Crown must file it within 60 days after service of the notice of appeal. In the informal procedure the Minister files a reply within sixty days after the notice of appeal is transmitted.

A general procedure reply must set out, among other things, the facts admitted and denied and the issues to be decided. The Crown's assumptions are also set out in the reply.

Why the assumptions matter

When the CRA assesses you, it relies on certain facts it has taken to be true, such as what an expense was for or what a property was worth. The reply lists these. Reading them closely tells you what the CRA thinks the case is about and where your evidence needs to be strongest.

Who must prove what on each assumption is a legal question that depends on the facts of your case, and it is worth discussing with a lawyer before you decide how to respond. One rule is clear: in the general procedure, allegations of fact in your notice of appeal that are not denied in the reply are deemed admitted.

How to respond

In the general procedure you may file an answer to the reply under Rule 45, within thirty days after service of the reply. The Court may extend or abridge any time in the Rules on just terms, but do not count on that.

What happens after the reply

In the general procedure, each party files and serves a list of documents within thirty days following the closing of the pleadings. A party may apply for an order requiring a full list of relevant documents.

There is also examination for discovery. A person examined must answer proper questions relevant to a matter in issue, must notify the other parties if an earlier answer was wrong or incomplete, and a party may read the adverse party's discovery evidence into its own case at the hearing.

In the informal procedure, the Court fixes the hearing date and is not bound by legal or technical rules of evidence. Judgment must be rendered not later than ninety days after the hearing concludes, except in exceptional circumstances. A written settlement offer can also affect costs in either procedure.

What to do next

Frequently asked questions

What are the CRA's assumptions of fact?

They are the facts the CRA took to be true when it assessed you, and they are set out in the Crown's reply. They show you what the CRA will rely on at the hearing.

How long do I have to answer the reply?

In the general procedure, any answer to the reply is filed within thirty days after service of the reply. In the informal procedure, the steps after the reply can differ, so it is worth confirming them with the Court or a lawyer.

What if I ignore something in the reply?

The reply sets out admitted and denied facts and the issues to be decided, and in the general procedure you may answer it within thirty days after it is served. What follows if you leave a point unanswered depends on the facts of your case, so it is worth confirming with a lawyer before the thirty days run out.

Can the case settle after the reply?

Yes. With your written consent the Minister may reassess at any time to dispose of an appeal. A written settlement offer can also affect costs in the general procedure.
