What happened: The deal begins in 2027-28 and runs through 2034-35. The 20-year-old defenceman was entering the final year of his entry-level contract.

Why it matters: Vancouver gains long-term cost certainty before Buium could reach restricted free agency. The commitment also places considerable weight on his continued development.

What to watch: Buium's role during the 2026-27 season will offer the next measure of that projection before the extension begins.
