Domi said he treasures the opportunity to wear a Canadiens jersey.
"You get a chance to put on a Montreal Canadiens sweater, it's top-notch and one of a kind," he said. "You enjoy every second of it. It's a huge honor to represent that logo and the people that played before you. It's a special opportunity. I'm really excited."
The 23-year-old also is excited to show he can get back to being an impact player. He was third among NHL rookies with 52 points (18 goals, 34 assists) in 2015-16 but didn't reach that mark in the past two seasons. He had 45 points (nine goals, 36 assists) in 2017-18 and scored nine goals each of the past two seasons.
Domi said his play simply wasn't good enough, but he's not dwelling on the past.
Those two seasons were in Arizona. His mind now is fully set on Montreal.
"I had a great time in Arizona. I enjoyed every second of it, made lots of friendships with teammates, and there will be memories … for the rest of my life," he said. "Very thankful for that. At the same time, new chapter in Montreal, arguably the most historic franchise in all sports, not just hockey. Pretty amazing, and very humbled to be part of it, really excited to get started."
