The tournament feature Canada, England, New Zealand and the U.S. with doubleheaders scheduled for Calgary, Red Deer and Edmonton on June 27, July 1 and July 5, respectively.
"We are two years away from the next World Cup," Ratier said in a statement Thursday. "It is time for young or new players to have their chance and for the returning players to take the lead. I am expecting a strong chemistry during this Super Series.
"Team culture is the key and the team will always be more important than individuals."
Tyson Beukeboom, Latoya Blackwood, Andrea Burk, Olivia DeMerchant, Mary-Jane Kirby, Barbara Mervin, Jacey Murphy, Laura Russell, Maria Samson, Amanda Thornborough, Brittany Waters and Julianne Zussman are the returning World Cup players.
It's the first outing for the Canadian women since the World Cup, where Canada finished runner-up to England.
Ratier will announce his captain at a later date.
