Sanctioning Versus Course Certification 

​

• Athletics Ontario Sanctioning is concerned with risk management and the safety of an event. Sanctioning is valid for one year and is subject to yearly review and re-application.

• Athletics Canada Course Certification ensures that a course has been accurately measured in accordance with international standards*. A Course Certification is valid for 10 years (5 years for IAAF/AIMS certifications), or until the course changes.  The Athletics Canada Course Certification ensures the races are measured accurately. A list of these races can be found by visiting the Athletics Canada Certified Courses List.
