Lachance, the son of former NHL player Scott Lachance, put on a show when he scored his first goal on the power play after the Warriors took a 5-minute major.
Lachance managed to net his second goal on another power play, assisted by Montreal prospect Lane Hutson and his brother Quinn Hutson, which put the team up 3-0 at 12:50.
The 20-year-old left-winger was drafted by the Oilers in 2021 in the sixth round, 186th overall. The Terriers who are off to a great start have a record of 10-4-1 and hold the projected future first overall draft pick in the upcoming 2024 Entry Draft in Macklin Celebrini.
