Canada’s Public Safety Minister Dominic LeBlanc promised an “internal review” to get to the bottom of the screening process that seemingly failed to detect a known terrorist before granting him citizenship.

LeBlanc’s statement comes after a few days of stalling and deflecting from the Liberals since news broke that 62-year-old Toronto resident, Ahmed Fouad Mostafa Eldidi, and his son, were arrested for planning a terrorist attack in Canada. Despite allegations of the father’s involvement in dismembering an individual on behalf of ISIS, as per a 2015 ISIS video, Eldidi was somehow granted citizenship.

LeBlanc told reporters on Wednesday that “The internal reviews in terms of the security screen process with the department of IRRC are ongoing.”

The Minister further said the chronology of the matter is still unclear. “There have been some public allegations around certain information. It might be interesting to know when that information came to light and when that information was in the hands of which decision maker,” he said.

The RCMP arrested Eldidi and his 26-year-old son, Mostafa, at a hotel north of Toronto on Wednesday, as they allegedly prepared to launch a terrorist attack for ISIS. Authorities seized a machete and an axe from them. Moreover, Eldidi’s son is not Canadian, according to Global News.

Intelligence gap

The report further indicated Eldidi came to Canada after 2015, meaning there appears a gap between the ISIS video that allegedly includes Eldidi, and the Canadian government granting him citizenship.

The Conservative Party is calling for an emergency meeting of the House of Commons public safety committee to investigate the issue. “This is a serious failure on the part of the Trudeau government to protect Canadian citizens from terrorism,” said Andrew Scheer, Conservative House Leader. “We need to know how someone with these alleged ties was able to come into our country and become a citizen.”

The Canadian Border Services Agency (CBSA) told Global News they were “unable to provide information”  regarding what screening was done on the Eldidi father. CBSA said their decision was “based on the information available at a moment in time.”
