But times are changing.

From a distance, it looked like mad ravings scrawled all over the walls of Mississauga’s St. Aloysius Gonzaga Secondary School.

Up close, it was clear this graffiti vandalism attack was part antisemitic, part anti-globalist, and part conspiracy theory.

And Mississauga’s mayor is very upset about it.

“Disgusting,” Mayor Carolyn Parrish said. “It’s disgusting no matter where such vile graffiti is found — but even more disheartening when at a school.”

Peel Regional Police are on it. So was a graffiti-moving spray-wash company.

“Police received a call at (about) 7:18 am (Tuesday) in relation to graffiti on the side of the building as well as on the ground near the front entrance of the school” near Glen Erin Dr. and Eglinton Ave., said Peel police spokesperson Const. Laurie McCann. “Police have attended and our hate crime unit has taken carriage of the investigation.”

They have lots of cameras to work with to help identify the culprits.

The vandals were not there for a short period of time. They marked the place up extensively. There were disturbing messages spraypainted or written on the walls of the high school and adjoining Erin Meadows Community Centre. Messages were also left behind on the sidewalk and entrance out front.

Nasty stuff, too.

“Israel kills kids” was one message, while “Israel spit on Christians, they hate the world” was another.

“Allahu Akbar” was also written there, as was “humanity vs Satan.” There were also references to Stanley Kubrick’s Eyes Wide Shut movie and the “Committee of 300″ conspiracy theory.

“This wasn’t just vandalism; it’s intimidation, pure and simple. When a school and community space are covered in messages that demonize and target Jews, it creates fear, isolation, and risks fuelling further violence,” said Michelle Stock, vice president, Ontario, at the Centre of Israel and Jewish Affairs (CIJA). “The Jewish and Catholic communities have deep, enduring ties, and we will not be divided by hate.”

This was a very clear message: Anger and bigotry.

“The appalling graffiti found today on a high school and a community centre in Mississauga is further evidence of the dangers of allowing hate and division to fester online,” said Richard Robertson, director of research and advocacy with B’nai Brith Canada. “We have allowed the spread of disinformation and inciting rhetoric to become normalized, creating a permissive environment where individuals are emboldened to act on their conspiratorial and antisemitic beliefs.”

B’nai Brith worries about what could come next

“Today it was vandalism, tomorrow it may be something far more sinister,” Robertson said. “Without concrete actions to confront hate and intolerance, we risk the further corruption of our national values. Our leaders must act now to confront the extremism and radicalization threatening our society.”

Parrish said there is no room or tolerance for something like this is in a city that prides itself on being safe and welcoming.

“Mississauga is an incredibly multicultural city which prides itself on shared Canadian values,” Parrish said. “So sad to see this.”

It was the second high-profile incident at this high school and community swimming pool, library and gym this year.

Peel cops made an arrest in February of two men and charged with them with gun counts in the hallway that sits in-between the school and recreation area.

There have been no arrest so far in this incident, but stay tuned because, in addition to extensive security cameras at this location, across the street in the Erin Mills Town Centre there is a massive number of cameras.

These criminals left behind a mark that just may help police track them down.
