There is a total of 40 classes available, with two or three classes per level of swimmer, a city spokesperson said in an email. Each class has a maximum of four to six participants, depending on the class level. As of Monday afternoon, many of the classes were already full, with waitlists. The first intake of classes start on May 2, and run every Sunday in May and June. Further class intakes are planned for later in the year. For kids in pre-school classes up to Swim Kids Level 4 classes, a parent will be required to be in the pool to supervise, as instructors are not allowed to be in contact with the students, under public safety rules.
