Former NHL forward Mikhail Grabovski has been charged with assault after what police describe as an alleged postgame confrontation at a youth hockey rink in Markham, according to York Regional Police. The alleged victim, identified in court documents as the coach of the opposing team, was treated for minor injuries at a nearby hospital. Grabovski is set to appear in Newmarket court on June 12 and was released on conditions that bar him from contacting the other coach.

Police response and scene

York Regional Police say officers were called to the Markham Village Community Centre near Highway 7 and Markham Road at about 10:50 p.m. on March 14 after reports of an assault during a youth hockey event, according to CityNews. When officers arrived, one male suspect was taken into custody and charged with a single count of assault, police said, and the alleged victim was transported to hospital with minor injuries. Investigators also acknowledged the existence of a video of the incident but said it cannot be released because it might identify the victim.

Charges and court schedule

Court records show that an assault charge was sworn on March 30 and that Grabovski is scheduled for a first appearance on June 12 in Newmarket, Ontario, according to Sportsnet. The documents allege he assaulted York-Simcoe Express coach Warren Cooper and include a signed undertaking that forbids Grabovski from contacting Cooper or going to locations where the coach is known to be. The listed charge is one count of assault.

The coaches and the game

Grabovski is listed on the Markham Waxers website as head coach of the club’s under-15 program, according to the Markham Waxers. Court documents name the alleged victim as Warren Cooper, head coach of the York-Simcoe Express, as reported by Global News. Police say the alleged altercation took place after an under-15 playoff game at the Markham Village Community Centre, a setting where hockey emotions clearly carried past the final buzzer.

League response

The Ontario Minor Hockey Association says it is aware of the situation and “does not condone this type of behaviour,” according to Sportsnet. The organization added that it will not comment further while the police investigation is underway. League officials and local clubs have stressed the importance of keeping benches and hallways calm, especially in playoff season when tensions can run hotter than the arena coffee.

Grabovski's hockey background

Grabovski played 10 seasons in the NHL, including five with the Toronto Maple Leafs, and appeared in 534 regular-season games, according to ESPN. Since retiring in 2019 he has worked in coaching and player development. That includes international roles and operating the Nitro Hockey program while also coaching with the Waxers, according to the club bio on Markham Waxers.

Legal note

The allegation against Grabovski is a criminal charge, and he is presumed innocent unless and until proven guilty in court. Court documents and police statements indicate the case will proceed in provincial court, and Grabovski’s undertaking, including the no-contact order, remains in effect while investigators and prosecutors consider their next steps, according to Global News.

What to watch next

York Regional Police are asking anyone with video or other information related to the March 14 incident to reach out to investigators, according to CityNews. The matter is now on the provincial court calendar for June 12, and local hockey officials say they will wait for the criminal process to unfold before considering any internal discipline. For now, Grabovski remains under court-ordered restrictions while the investigation continues and the hockey community watches what happens next.
