To become an official in swimming requires some knowledge of the sport.
You can gain that knowledge very quickly by helping out at swim meets. All swim competitions must follow the Swimming Canada/World Aquatics rules and as such must be properly staffed to provide a consistent and fair competition environment. The Officials Development Program (ODP) approved by Swim Ontario, encourages clubs to engage their official’s progression through levels of certification, complementing the club’s ability to host and/or assist at meets. Better officiating means better and more efficient meets.
Certification as a swimming official follows the Swimming Canada Certification Pathway with 5 levels of national certification. Additionally an official can be certified as a PARA swimming official and/or Open Water swimming official.
The Swimming Canada Certification Pathway was updated in May 2025 to clarify the requirements for the Chief Recorder and Chief Judge Electronics positions.
The requirements for certification, evaluations procedures and resources for each level of the certification pathway and beyond are available by clicking the level of certification found below.
To better monitor the progression of officials through the updated certification pathway—from Level 2 to Level 4—Swim Ontario introduced two new designations at the start of the 2023-2024 season: Level 2 Developing Referee and Level 3 Referee. These terms were created to reflect the evolving Referee position and to support tracking throughout the development process.
Officials' progress can now be tracked in the registration system using credentials that only Swim Ontario can apply to an official’s profile. For full details, officials should refer to the Referee Pathway & Requirements guide and Level 3 Certification requirements for details.
The Official Development Pprogram procedure will be in effect for the 2024-25 season with adjustments outlined HERE.

A level 2 official has gained additional experience through clinics and working at competitions and is certified in the more than 2 junior level and/or administrative positions.
A Level 3 official has completed all clinics with the exception of the referee clinic and is able to work those positions at a competition. They begin to teach clinics with mentors. The focus of Level 2 to Level 3 certification is to gain more experience and progress through the various positions and begin learning and working the Referee position.
A Level 4 Senior Official has focused on self-improvement through travel afield in the region and the province, gaining experience with different types of competitions and has been active in providing mentoring to upcoming officials at the local club. They have gained experience in not only the referee position but other deck positions. They may be assigned as a Competition Coordinator.
The more diversified experience the candidate gains as a referee and continues to gain as an official in other roles on deck, will serve them positively in their development as an effective and successful Referee.
A level 5 Master Official is the highest level of certification in Canada. A Level 5 official can be assigned as Competition Coordinator and can teach all clinics including the Referee clinic. They can begin providing referee assessments for upcoming officials. They have diversified their experience with not only referee roles but in other positions on the deck at competitions to help them positively in their development as an effective instructor, mentor and evaluator.
In order to remain an active Level V official in Canada, an official must:
Officials who do not work or instruct as required may apply to their Provincial Officials Chairperson for reinstatement, at which time a review of clinics may be required for certain positions.
A para swimming official is an official that has knowledge of the rules of para swimming and experience officiating at meets with para swimmers in attendance. There is a Domestic Pathway and an International Pathway with three levels of certification.
An Open Water official has knowledge of the rules of Open Water swimming and experience working at Open Water events. There are three levels of certification for Open Water officials.
Swim Ontario would like to recognize the hard work the following officials have done to achieving their next level of certification.
