Ontario Police Warn Students Over 'Senior Assassin' Water Gun Game

Ottawa students wrapping up the school year may want to think twice before joining in on a viral end-of-year tradition, as Ontario police are sounding the alarm about a game called 'Senior Assassin' — and the serious consequences it can carry.

What Is 'Senior Assassin'?

Senior Assassin is an elimination-style game popular among graduating high school students across Canada and the United States. Players are assigned a target and must 'eliminate' that person by hitting them with a water gun — all while avoiding being hit themselves. The last player standing wins.

While the game might sound like harmless springtime fun, police across parts of Canada are now warning that it poses real safety risks — not just for participants, but for bystanders too.

Why Police Are Concerned

The core concern is straightforward: to the untrained eye, a water gun can look like a real firearm — especially from a distance or in a moving vehicle. Officers worry that members of the public who spot students sneaking around with what appears to be a weapon could call 911, triggering a potentially dangerous police response.

"The public doesn't always know it's a game," police have noted in warnings circulated to schools. In high-stress situations, that kind of confusion can escalate quickly.

An Incident That Crossed a Line

Beyond the optics problem, one Ontario community is now dealing with a more serious allegation. The Ontario Provincial Police (OPP) have launched an investigation after students allegedly used the game as cover to spray an unhoused Indigenous man with a water gun.

The incident has drawn sharp criticism, with advocates pointing out that targeting a vulnerable person — regardless of the game — is not a prank. It's harassment, and potentially a criminal matter.

Police have not yet announced charges, but the investigation signals that the game's fun-and-games framing doesn't shield participants from accountability when their actions harm others.

What Ottawa Parents and Students Should Know

School boards across Ontario have been quietly fielding questions about Senior Assassin for several years, but this season's incidents have pushed the issue into the public spotlight. For Ottawa students heading into exam season and graduation festivities, the message from law enforcement is clear: know the risks before you play.

If you're participating, be aware that:

  • Running through neighbourhoods with a fake gun can lead to a police call
  • Targeting strangers — especially vulnerable individuals — can result in criminal charges
  • School property and school events are generally off-limits, and violations can affect graduation standing

For Ottawa parents, it's worth having a direct conversation about why context and judgment matter, even in games that seem low-stakes.

The Bigger Picture

Senior Assassin isn't going away — it's been played for decades and each spring brings a new wave of players. But as the OPP investigation shows, the game's consequences can be very real. Ottawa's graduating class of 2026 has plenty of ways to celebrate the end of an era. Staying on the right side of the law is a good place to start.
