How is asking IRCC to reconsider different from filing a formal appeal?

A reconsideration request is an informal ask to the same decision-making body, usually IRCC, to look again at its own decision, often because of a claimed error, an overlooked document, or new information. It is not a formal legal proceeding: there is no fixed process, no guaranteed deadline, no right to a hearing, and no obligation on IRCC to respond to it at all, let alone reopen the file.

A formal appeal, such as one to the Immigration Appeal Division, or an application for judicial review at the Federal Court, is entirely different. Both are structured legal processes with defined filing deadlines, formal rules of procedure, and a decision-maker legally required to consider and rule on the matter, with defined remedies available if the applicant succeeds.

Reconsideration can sometimes be faster and simpler if it works, since it avoids a formal proceeding altogether, but its informality is also its weakness: there is no guarantee IRCC will engage with it at all. Because filing a reconsideration request does not pause the strict deadlines for a formal appeal or judicial review, protecting those deadlines should never be set aside while waiting for a reconsideration response.
