Canada taking review of immigration screening of terror plot suspects 'extremely seriously,' PM Trudeau says

Prime Minister Justin Trudeau says the federal government is taking an internal review into the immigration and screening of a father and son recently charged in connection to an alleged foiled Toronto terror plot 'extremely seriously.'

Prime Minister Justin Trudeau says the federal government is taking an internal review into the immigration and screening of a father and son recently charged in connection to an alleged foiled Toronto terror plot "extremely seriously."

"This is obviously a very serious situation that the Minister of Public Safety is ensuring there [is] a full follow up and understanding on exactly how this happened. I know investigations are ongoing," Trudeau told reporters on Monday.

In July, the RCMP arrested Ahmed Fouad Mostafa Eldidi, 62, and Mostafa Eldidi, 26, in Richmond Hill, Ont. The two — whom police initially said they understood both to be Canadian citizens— were "in the advanced stages of planning a serious, violent attack in Toronto," authorities found.

The pair are facing a series of terrorism-related charges, including conspiracy to commit murder for the benefit of, at the direction of, or in association with the Islamic State.

Most of the charges stem from alleged activities undertaken in Canada. But the father was also charged with committing an aggravated assault outside the country in June 2015 for the benefit of the terror group.

Citing unnamed sources, Global News reported last week that the father immigrated to Canada after allegedly being filmed taking part in ISIS violence overseas, and that his son does not hold Canadian citizenship. CTV News has not independently verified this reporting.

When pressed further by reporters on whether the federal government knows more about how the father and son immigrated to Canada, Trudeau would not specify.
