The Halifax, Nova Scotia native 64 games for the Vancouver Canucks between the 2020-21 and 2021-22 seasons, registering 17 points (eight goals, nine assists), 16 penalty minutes and was a plus-one. At the conclusion of the 2021-22 campaign, Highmore was set to become a restricted free agent, however the Canucks decided not to issue him a qualifying offer, making him an unrestricted free agent.

We should find out just after 2 pm ET (11 am PT) if Matthew Highmore clears waivers and will be assigned to the American Hockey League. The San Jose Sharks get the first crack at making a waiver claim on Highmore given that they finished dead-last in the entire NHL last year, but it's probably a safe bet that he'll clear and join the Belleville Senators tomorrow afternoon.
