Timmins, 19, is in his third season with the Sault Ste. Marie Greyhounds (OHL), where he has tallied 35 points (6g/29a) in 30 contests while helping the Greyhounds to the league's best record. Selected by Colorado in the second round (32nd overall) of the 2017 NHL Draft, Timmins won a gold medal with Team Canada at the 2018 IIHF World Junior Championship in Buffalo. The 6-foot-2, 184-pound defenseman collected five points (1g/4a) during the event-including an assist on the game-winning tally in the gold-medal game against Sweden-and was a tournament-best +15.

"Conor had a great training camp with us and we are excited with the growth he's shown this season," said Avalanche Executive Vice President/General Manager Joe Sakic. "He's had another strong year in the OHL and played important minutes for Canada's gold medal team at the world juniors. We are proud to have him with our organization."

A native of St. Catharines, Ontario, Timmins led all Sault Ste. Marie defensemen and tied for fourth among OHL blueliners with 61 points (7g/54a) in 67 games last season. His 54 assists and +53 plus/minus rating were both team highs and ranked third and fourth, respectively, among OHL defensemen. He added eight points (1g/7a) in 11 playoff games, sharing the team lead in postseason assists.
