Canada’s Immigration Minister Jason Kenney said on Wednesday that he believes the Canadian parliament should consider stripping Canadians of their citizenship for acts of terrorism, after it was confirmed that a Canadian suspect was involved in the Bulgaria terror attack last July.

An opposition leader called the proposal a "knee-jerk response," AFP reported.

Kenney told reporters that the Canadian suspect in last year's fatal bus bombing in Burgas was born in Lebanon and only lived in Canada for a few years as a child.

"We believe he's likely a dual Canadian-Lebanese national who has not lived here as a permanent resident since the age of 12," Kenney said, according to AFP.
