The U.S. outshot Canada 39-8 on Tuesday.
"We have a young team and have less experience playing against that level of competition," McGregor said. "Our younger players played really well, we had some good chances and we did a lot of things well. The difficult thing to do against a team like [the U.S.] is to keep the game in reach, and unfortunately the third period got away from us.
"We are focusing on what we can do better each shift, each period and each day moving forward."
