2026–2027 math contest calendar for Canadian families

Choose a suitable grade and question format, then ask your child’s school about participation. Dates below apply to Canada; schools may set earlier internal deadlines.

Separate contest dates from deadlines

CEMC dates were checked on November 6, 2026. The CSMC / CIMC ordering deadline has passed. A future contest date does not mean registration is still open. Confirm changes with the organizer and participating school.

Dates use year–month–day. Grades follow the organizer’s Canadian system; Québec families should confirm the equivalent level with their school.

How to participate

CEMC participation is arranged through schools, not individual student registration. Ask the math teacher first; if the school does not participate, another participating school may accept the student. A TAC course inquiry does not register a contestant or confirm an exam location.

Choose a starting point

Grade level is one reference point. Try official past problems together and consider the reading, reasoning and written explanations required before choosing a contest. Competition preparation and regular math tutoring can be discussed separately.
