MacKenzie Weegar had a goal and two assists in the second three-point game for the Calgary Flames defenseman, while Michael Carcone and Jack McBain had a goal and an assist for Canada.

After Jan Drozg’s goal put Slovenia ahead in the opening period, Canada answered with a three-goal second period in Group B in the Latvian capital Riga.

Carcone equalized with a wrist shot 1:13 into the second period, Pierre-Olivier Joseph gave Canada a 2-1 lead and Milan Lucic doubled the advantage on a power play.
