Tyler McGregor scored a goal in every period to secure a hat-trick, and also added an assist, to help the Paralympic silver medallists to a 7-0 triumph at the Western Fair Sports Centre.

The first goal from McGregor was the game's opener, and the only one in the first period.

Corbyn Smith fed him the puck from the corner and he made no mistake in beating goaltender Lee Jae Woong.

James Dunn doubled the lead after 55 seconds of the second period, pouncing on the rebound from a Billy Bridges shot and poking it past Lee with Canada on the man advantage.

McGregor then notched his second of the game, flipping in a rebound from Dunn’s initial shot to make it 3-0.

Canada registered a third goal in the second frame from Smith, who finished off a slick passing play in front of the net from Dunn and Liam Hickey.

McGregor capped off his hat-trick midway through the third period before Micah Kovacevich’s first international goal made it 6-0, burying a cross-ice pass from Bridges.

Bridges bagged the final goal of the night, finishing off a move that included Zach Lavin and Dominic Cozzolino.

The competition features all three Winter Paralympic Games medallists from Pyeongchang 2018, with each team playing each other twice.

The round-robin format is set to run until Friday (December 7).

It will be followed by the final, between the two best teams, on Saturday (December 8).

Action is due to continue tomorrow when Canada take on Paralympic champions and holders the United States.

The Para Hockey Cup, previously known as World Sledge Hockey Challenge, was re-branded in June, with retail company Canadian Tire named as the title sponsor.
