The 19-year-old blueliner will play his fifth game of the season Monday against Carolina. The first season of his three-year entry-level contract kicks in if he plays in a sixth NHL game, which for the Bruins is Tuesday against the New Jersey Devils.
"Upper management will make that decision, but from our end of it, he's been really good," Bruins coach Claude Julien said. "He's better and better every game as he gains confidence. I've really liked his composure and vision of the game. He's been extremely good for us."
Before joining the Bruins at the start of the NHL season, Hamilton had 41 points in 32 games with the Niagara IceDogs of the Ontario Hockey League, and had a goal and an assist in six games for Canada at the 2013 IIHF World Junior Championship.
He said he's looking forward to having his status resolved.
"It will be really nice," Hamilton said. "I'm trying not to think about it too much. I'm just trying to work my hardest and keep playing my game."
