Markham Aquatic Club (MAC) provides the opportunity and encouragement for each of our swimmers to develop his or her full potential in competitive swimming in the pursuit of personal excellence.

Swimmers train in the world-class 10 lane, 50-metre Markham Pan Am Centre pool and several modern 8-lane and 6-lane 25-metre pools. Working with each swimmer's unique strengths, Head Coach Sean Baker, and his professional coaching staff are excited to continue MAC's winning tradition through hard work, dedication and training strategy.

MAC has produced swimming champions for over 40 years, from local club competitors to Canadian and U.S. University swimmers and from Provincial and National Level competitors to  Commonwealth and Olympic Games swimmers.

Building on our past successes, MAC continues to develop into a model of excellence committed to each individual and overall TEAM success, from the grassroots to Olympic level.

Each swimmer's progression is carefully crafted according to individual strengths and abilities, providing the structure and environment to advance at their optimum rate. 

Programs are divided into our competitive swimming program and our introduction to competitive swimming program named Olympic Prospects (OP).

MAC is operated by a duly-elected volunteer Board of Directors. Our swim training programs are delivered by top professional coaching staff. Parent volunteers perform multiple duties within the club, from swim meet officiating to serving on our Board and committees.

MAC provides the opportunity and encouragement for each of our swimmers to develop his or her full potential in competitive swimming in the pursuit of personal excellence.


MAC’s vision is to be the premier swim club for competitive swimming in Canada.


The principles by which we operate are:

Our Swimmers

First and foremost, every decision made by the Club is based on the impact to the swimmers.  The swimmers are the most important component of the Club and as such, our time, attention and resources are focused on delivering excellent swim training programs for our swimmers.

We strive to inspire and enable our swimmers to achieve excellence in the sport of swimming and in life while creating an environment where excellence is inevitable and fun!

Our Coaches

The Club values the knowledge and dedication of each coach.  Coaches will have a safe and enjoyable environment in which to work.  Coaches should have the opportunity to learn and grow as a coach and the freedom to make decisions and be accountable for the outcomes.

Our Officials

As a member of the swimming community we take pride in contributing to the sport by ensuring that we have well trained officials not only for our own meets, but for other clubs’ meets when called upon.

Our Members

As members we recognize our role is to support the swimmers, coaches, and Club in any way possible.  As a volunteer run organization the Club’s success is directly linked to the volunteering efforts of the members.

As not-for-profit, member-run organization we strive to provide value to our members, transparency of operations, proper governance, and the ability for any member to assist with the direction and operation of the Club.

Our Community

We aim to have a positive impact on our community by representing the City of Markham to the best of our ability both in and out of the water.
