Charest faces 57 charges, including sexual assault and breach of trust.
The latest alleged victim came forward recently and said she was sexually assaulted in Whistler, B.C., in the late 1990s.
The initial incidents allegedly took place in the '90s in Mont-Tremblant, north of Montreal, and in France, Austria, New Zealand and the United States.
The alleged female victims were all between 12 and 18 and Charest was in a position of authority as a coach.
Charest worked with Alpine Canada's women's development team between 1996 and 1998.
He has been detained since his arrest in March and has previously been denied bail.
The case is scheduled to resume July 21.
