Corey Perry, Matt Dumba, Derick Brassard join Team Canada's roster

Canada's roster for the 2016 IIHF world championship has increased to 21 players with the additions of NHLers Corey Perry, Matt Dumba, and Derick Brassard.

All three players have earned medals while representing Canada in past international competition.

Perry is a two-time Olympic gold-medallist and Stanley Cup champion with the Anaheim Ducks. Both Dumba and Brassard represented Canada at the IIHF under-18 world championship, with Dumba bringing home bronze in 2012, and Brassard earning silver in 2005.

"Fans know these three players well for their success in the NHL, but it's important to remember all three also bring international experience that will serve our team well as we begin our quest to defend gold," said head coach Bill Peters.

Team coaches and staff have arrived in Prague, Czech Republic, to prepare for the pre-competition camp that kicks off on Friday following player arrivals. The camp will include an exhibition game against the Czech Republic on Tues., May 3.

Canada opens the world championship in Moscow and St. Petersburg, Russia, against the United States on May 6, with preliminary-round games scheduled through May 17. The bronze- and gold-medal games will be hosted in Moscow on May 22.
