How do U16 and U18 athletes enter the national championships?

Under the Athletics Canada Technical Rules (December 2025):

• National U18 Championships: Athletics Canada associates aged 17 and younger in the year of competition who have either achieved the automatic qualifying standards or advanced through the qualifier section.
• National U16 Championships: Athletics Canada associates aged 15 and younger in the year of competition who have either achieved the automatic qualifying standards or advanced through the qualifier section.
• Athletes under 14 in the year of competition cannot enter the U16 Championships or higher (see the question on competing up).
• An athlete whose entry is rejected for any reason may appeal to Athletics Canada, whose decision is final.
• The affiliation (club or sponsor, and Branch) of every athlete is shown in the results.
• At national championships, an electronic device such as a laptop is mandatory for ranking athletes in the throws and horizontal jumps, and fully automatic timing is used.
