The 27-year-old defenceman is the latest recruit announced in another busy day of signings across the four teams taking part in the competition.
And Doucet insists his new man will be a player that will be exciting to watch in the five-week series.
“Dominic’s the kind of guy who wants to be the quarterback on the powerplay, you might say,” Doucet said. “He’s got some high end skills with the puck and that’s what made him interesting to us.
“He’s going to be exciting to watch and I’m really happy to work with someone like that and will use this series as an opportunity to show what he can do at pro level.
“He told me his dream is to play professional hockey so to get the chance and be that, even if it’s for only five weeks, he’s looking forward to it.
“Dominic coming here and showing what he can do in this series is a perfect fit for both parties and I’m super excited to see what he can do.”
Talbot-Tassi has spent the last five years at McGill University, playing almost 170 times, scoring 34 goals and picking up an impressive 131 assists in the Canadian USports League – a good figure for a blue liner.
For Doucet, it was a signing that resonated with him personally, having come from the same university himself before he turned pro 10 years ago.
“I’m delighted to finally recruit someone from my alma mater in McGill,” he added. “Dominic is a very skilled defenceman and had a very good career at university level.”
