Terms

By using the site you accept that it is general information, current to the sources read on 17 October 2026.

Information only

The pages describe publicly available dates. They are not tax, legal, or accounting advice. Official text on Government of Canada sites controls if a page here disagrees with it. Revenu Québec controls provincial Quebec dates, which this site does not publish.

Dates

The calendar is an expected list for 2027. It can be wrong if your year-end is not 31 December, if a provincial holiday differs from the calculated list, if the tax-shelter exception applies and you rely on 15 June anyway, or if a CRA page changes. You are responsible for what you file and what you pay. A filing date of 15 June 2027 does not move a payment date of 30 April 2027.

No warranty

The site is provided as-is, without a warranty of completeness. To the extent the law allows, Canada Self-Employed Calendar is not liable for results that come from using it.
