The CMO Qualifying Repêchage has been discontinued.
The 2026 edition of the Repêchage was the last of this annual competition series.
In past years, it was offered as a kind of “take home” competition to invited students who scored well, but just below the top group, on the Canadian Open Mathematics Challenge (COMC).
Starting in 2027, we will instead be increasing the number of people invited directly from the COMC to the Canadian Mathematical Olympiads (CMO/CJMO). This will also allow us to hold the CMOs earlier so that they don’t compete with spring break scheduling in March each year.
We retain this web page primarily to hold and offer freely the archive of questions and solutions so that motivated students can improve their abilities as they reach for higher results and the opportunity to eventually go to the International Mathematical Olympiad (IMO) as part of Math Team Canada.
Best wishes from the CMS Competitions group!
