The Canadian federal public safety minister said on Sunday that Canadian security agencies are "exercising increased vigilance" following the deadly shooting that occurred last weekend at a rally for former U.S. President Donald Trump in Pennsylvania.

Dominique LeBlanc posted a series of messages on the social media platform X, stating that he had been briefed by public safety officials in Canada, the RCMP commissioner, and the CSIS director, adding that these organizations are in contact with their American partners.

LeBlanc wrote: "I have complete confidence that they will continue to ensure the safety of Canadians."

The Governor of Pennsylvania said that one participant in the march, named Corey Cumbriatore, was killed while trying to protect his family from gunfire, while two others were seriously injured.

The shooter, later identified by the FBI as 20-year-old Thomas Matthew Crooks from Bethel Park, Pennsylvania, also died. U.S. law enforcement officials stated that the shooting is being investigated as a potential assassination attempt.

LeBlanc added: "The information we have so far shows no connection to Canada. However, our security agencies and law enforcement are ready to assist our American counterparts in any way."

A retired RCMP officer said on Sunday that he does not expect significant repercussions for the security provided to Canadian politicians following the shooting.

Chris Mathers, who is now a special advisor, believes that the security provided to the Prime Minister and opposition leaders aligns with the threat levels against them and is adjusted accordingly.

Mathers added in an interview: "I don’t think there will be any real repercussions in the end; security is always tightened after an incident, and that’s just human nature."

Mathers noted that security experts will examine what happened to understand where things went wrong on Saturday and will implement changes to their procedures as necessary. In a speech on Sunday before the American public, President Joe Biden also ordered an independent security review of the events leading up to the attack on his political rival.

But in this case, Mathers stated, it is clear that individuals are not supposed to be on the surface near a high-profile figure, as Crooks reportedly was.

He said: "So there’s not much to learn from this other than that, you know, maybe you should make sure people are doing their jobs."

Neither of the major opposition parties nor Prime Minister Justin Trudeau's office wanted to comment beyond their initial statements condemning the American shooting when contacted about security on Sunday.

However, the leaders of the three main federal parties unequivocally condemned the shooting in the immediate aftermath, and LeBlanc echoed those sentiments on Sunday.

He wrote, "Violence erodes democracy, and we will always stand against it. Regardless of our political differences, violence is never the solution."

"Such actions are an assault on all of us."

Politicians in Canada have not been immune to rising threats in recent years, with increased security for some members of parliament, including several ministers.

In one notable case, a gunman shot and killed a lighting technician on September 4, 2012, while the Parti Quebecois and its former leader Pauline Marois were celebrating their victory in the provincial elections.

While the Prime Minister and the Governor General are given permanent protection details, other members of parliament, ministers, senators, and party leaders receive protection "on a case-by-case basis," Canadian police stated earlier this year.

RCMP Commissioner Mike Duheme said in May that he would like to see a new law that makes it easier for the Crown to charge individuals who threaten elected officials.

Canadian Prime Ministers also condemned the shooting that took place on Saturday. They are meeting this week in Halifax for a Council of the Federation meeting.

Newfoundland and Labrador Premier Andrew Furey said on Sunday at an unrelated news conference: "In democracy, it’s important - it’s a requirement - it’s a key element that there are disagreements in the wings and robust debate."

"But there’s no place and there can never be a place for violence."

Mathers noted that the United States is a different political beast than Canada given the vast number of weapons among the general public.

Mathers said, "The playing field is completely different in the U.S. regarding gun culture, but Canada is not. You know, people can get guns everywhere in the United States."

Mathers added that lone attacks are not always predictable for security details unless perpetrators post materials online and authorities are alerted to them.
