What happened: The agreement came 11 days before Sept. 15, after which re-signing teams can offer no more than seven years. Buium remains on his entry-level contract for the upcoming 2026-27 season.

Why it matters: The term secures the 20-year-old defenceman through a rebuild with no fixed playoff deadline. Vancouver also removes Buium's 2027 restricted free agency as a roster-planning variable.

What to watch: Attention turns to Buium's role in training camp as Vancouver prepares for 2026-27.
