Ex-Maple Leafs forward Mikhail Grabovski charged after alleged assault at Markham youth hockey game

The former Toronto Maple Leafs forward has been charged with assault, according to court records filed in Newmarket on Monday.

Those records say Grabovski was arrested earlier in March after an alleged incident involving Warren Cooper, who is listed as the head coach of the York-Simcoe Express under-15 team.

York Regional Police said officers were called to a Markham community centre at 10:50 p.m. on March 14 after a report of an assault.

Police also said the alleged victim was taken to hospital with minor injuries, which gives this story a level of seriousness that goes far beyond a rink-side dispute.

A signed undertaking form shows Grabovski agreed not to communicate directly or indirectly with the complainant and not to attend places where that person is known to be.

The timing matters because the allegation is tied to a youth hockey setting, where coaches are expected to bring structure and control behind the bench.

The reported altercation is tied to an Express game against the Markham Waxers earlier this month, and that detail puts both benches under a brighter light.

Grabovski is identified as the head coach of the Waxers U14 Triple-A and U-15 teams, while his team biography also points to a U16 AAA role for the 2026/2027 season.

That makes the story bigger than a former NHL name in court. It now touches current player development, bench leadership, and the atmosphere around elite minor hockey in the GTA.

Grabovski spent 5 seasons with the Maple Leafs from 2008 to 2013 and was one of the more recognizable forwards from that era.

In his first full season in Toronto, he posted 20 goals and 48 points, leading Eastern Conference rookies in scoring and carving out a real spot in the club's top six.

He later played for the Washington Capitals and New York Islanders through the 2015-16 season before retiring from pro hockey in 2019.

Since then, he has moved into coaching and management, with time in the KHL and with Belarus' national program, which is why this charge lands with extra weight inside hockey circles.

For minor hockey families, that's the part that hits hardest. This is no longer about what Grabovski once was in the NHL. It's about whether a coach tied to young players can keep that role while the case moves through court.
