Tony Clement and Kevin O’Leary have added their names to the list of high-profile Conservatives criticizing candidate Kellie Leitch’s plan to screen immigrants for anti-Canadian values.

O’Leary told The Canadian Press Monday that Leitch’s proposal is “totally un-Canadian.”

“I wouldn't be here if that kind of mandate existed," said the TV star and businessman, whose mother immigrated to Canada from Lebanon.

Clement addressed Leitch’s proposal Monday on CTV’s Power Play, stating: “I just think we have to work on workable solutions.”

“The Conservative Party that I want to lead is a party that does support Canadian values but it’s also going to be a pro-immigration party…” he added.

Clement held a press conference to outline his plan to protect Canadians from terrorism Monday, which he said includes working with “moderate mainstream Muslim Canadians,” a pilot project to study video-conferencing with potential immigrants, monitoring charities for signs of terror financing and jailing people suspected of terrorism.

"If they are so dangerous to the Canadian population that they deserve a peace bond slapped on them, I would put it to you that unless we can surveil them 24/7, they should be incarcerated," Clement told a news conference Monday in Ottawa.

He cited the case of Aaron Driver, an ISIS supporter who was killed last month in a confrontation with police in Strathroy, Ont., as evidence that peace bonds aren’t good enough and that suspects should instead be jailed.

RCMP were not aware of Driver’s imminent threat until they were alerted by the FBI.

Clement told Power Play that he believes there is a way to jail suspected terrorists in a way that is “legal, judicially proper and will protect us.”

“You have to go through a legal process but you also have to protect society and make sure that people know what’s in their midst,” he said.

Interim Conservative leader Rona Ambrose, leadership candidates Michael Chong and Maxime Bernier, and former cabinet ministers Jason Kenney and Lisa Raitt, have also come out against Leitch's proposal.
