MSO Rules of Competition

2013-2017 Rule Book

The 2013-2017 Rule Book was developed and maintained by the Rules Committee of Masters Swimming Canada (MSC) and contained Canadian variations or interpretations of FINA rules.  In 2017, MSC abandoned the Rule Book and opted to refer only to the FINA Rules. Ad hoc rule changes are now only posted on the MSC website.

The 2013-2017 Rule Book is published here. It has been updated with the minor changes to the breaststroke and backstroke rules of November 2014 to ensure consistency with the rules applied to all masters swimming competition in Canada. A MSO technical committee will carefully review the other FINA clarifications and publish a new domestic Masters rule book.

MSO WARM-UP RULES – updated 2017-12-26 (WORD version for insertion into meet package)



Swimmers who attended MSO Provincials last March, showed patience and flexibility when the meet suddenly changed going from a double-ended to a single-ended format.  The change was the result of the City’s revised risk assessment that resulted in the elimination of diving in the shallow end.  Since then Swim Canada issued revised pool depth Guidelines and communications for both competition and training.

Masters swimming rules have always been closely aligned with Swim Canada rules and MSO will continue to do so. While we finish updating the MSO Rules of Competition, including the Facilities Guidelines, we direct you to the Swim Canada statements and communications.

Diving for both Competition and Training
