Mackenzie Entwhistle and Nick Suzuki also scored for the Ontario Hockey League champion Storm while Sean Durzi chipped in with three assists. Anthony Popovich made 22 saves for the win.
The 19-year-old Toropchenko, a St. Louis Blues prospect, has been on fire after scoring seven goals in the OHL championship to beat the Ottawa 67’s in six games and advance to the national major junior hockey championship.
Vincent Marleau and Jakub Lauko found the back of the net for the Quebec Major Junior Hockey League champion Huskies, who entered the four-team tournament as the No. 1 ranked club in the Canadian Hockey League.
Samuel Harvey stopped 24-of-29 shots in defeat.
Guelph continues round-robin action against the host Mooseheads on Sunday in a matchup of squads that won their tournament openers. Halifax downed the Western Hockey League champion Prince Albert Raiders 4-1 on Friday to kick off the CHL championship.
Storm manager/coach George Burnett made five major trades between Jan. 4 and the Jan. 10 OHL trade deadline, helping bring Guelph to its sixth Memorial Cup appearance. The Storm went 22-5-3 down the stretch, yet they were still left off the CHL top-10 rankings.
"I wouldn’t put much thought into that," said a confident Burnett.
Marleau opened the scoring less than three minutes in, taking the puck on a solo rush and beating Popovich glove side from the top of the face-off circle with a stoppable shot.
After Marleau’s goal the rest of the period belonged to Toropchenko.
Harvey made a fine glove save on Suzuki to keep it a one-goal game, but couldn’t stop Toropchenko after a turnover led to him being alone in front to snap the puck past the Huskies netminder at the 11-minute mark while shorthanded.
Toropchenko wasn’t done either, as he backhanded one past Harvey 2:07 later on his next shift to give Guelph a 2-1 lead.
The Russian forward then received a beautiful outlet pass from defenceman Sean Durzi and went in on a breakaway, beating Harvey five-hole for a first-period hat trick and a 3-1 Storm lead at 18:23.
Entwhistle took a pass from captain Isaac Ratcliffe on a 2-on-1 and beat Harvey top shelf 3:20 into the second for a 4-1 lead on a play that started with another strong outlet pass from Durzi.
Lauko cut Rouyn-Noranda’s deficit to 4-2 with a solid individual effort at 11:16 of the second when he took a pass at Guelph’s blue line, turned on his speed and beat the defender wide before cutting the crease and sliding the puck past a sprawled Popovich.
Lauko’s goal seemed to spark the Huskies as they kept up the pressure until Suzuki finished off a 2-on-1 with Durzi at 19:12 to head into the second intermission up 5-2.
Popovich made up for the early goal he let in with two of his biggest saves in the third to preserve the victory.
