According to Sportsnet, the NHL has notified the NHLPA that it "wants to modify or terminate the existing collective bargaining agreement," which has led several teams including the Flames to cancel their annual rookie tournament in Penticton, BC because of concerns about another potential work stoppage.

More to come as the story develops.
