Aaron Dahl, a nationally recognized coach recruited to work in Newfoundland and Labrador last fall, has been suspended from his position with the St. John's Legends Swim Club.
The club announced the news in an internal letter sent to the parents of members of the team, which trains children and adolescents in different age groups.
The club is not commenting on the suspension, other than to say that it involves an incident that happened over the weekend which was alcohol-related.
The club said no other swimmer or coach was involved.
Cathy Dornan, a member of the board, said the suspension is an employee matter and will not be discussed publicly.
When Dahl arrived in St. John's last fall, the club described him as an experienced coach who helped place seven swimmers on Canada's 2012 Olympic team.
"Aaron is a well-known and highly qualified swim coach with a resume that is very impressive. He is highly regarded in Canada's swimming community as one of Canada's leading age-group coaches," the club said in a statement at the time.
Dahl is also the head coach of the men's and women's varsity swim teams at Memorial University. It is not clear if he still holds that position.
CBC News contacted Dahl for an explanation, but he refused to comment.
