The Emergency Committee in Ottawa is holding a hearing today, Tuesday, on whether Members of Parliament will discuss summoning ministers to testify regarding the immigration and security screening of a father and son who were recently charged in connection with an alleged failed terrorist plot in Toronto.

The Public Safety and National Security Committee in the House of Commons is meeting to vote on calling the Minister of Public Safety, the Minister of Immigration, and relevant federal officials to answer questions related to the case.

In July, the Royal Canadian Mounted Police arrested 62-year-old Ahmad Fouad Mostafa Al-Didi and 26-year-old Mostafa Al-Didi in Richmond Hill, Ontario, whom the police accused of being "in the advanced stages of planning a serious and violent attack in Toronto."

The two face a range of terrorism-related charges, including conspiracy to commit murder on behalf of ISIS or at its direction or in association with it. The men are scheduled to appear in court later today.

Most of the charges stem from alleged activities they conducted in Canada. However, the father was also accused of committing aggravated assault abroad in June 2015 on behalf of the terrorist group.

Citing unnamed sources, Global News reported that the father immigrated to Canada after being filmed participating in ISIS violence abroad, and that his son does not hold Canadian citizenship. CTV News has not independently verified this report.

Earlier this month, the Conservatives led a call for hearings on the matter, stating that Canadians deserve answers and assurances regarding potential shortcomings in the screening process.

The New Democratic Party supported the proposal, expressing interest in expanding it to include investigations into other cases of allowing criminals and individuals linked to oppressive political regimes to enter — paving the way for today’s hearing.

In the face of scrutiny over how the two were allowed into Canada, Public Safety Minister Dominic LeBlanc confirmed last week that major federal agencies are conducting an internal review of the timeline and circumstances of this case.

He accused the opposition of politicizing an active criminal matter — and when faced with the possibility of being summoned to testify — he said he would have more to say publicly, when appropriate.

While he seemed to cast doubt on some circulating information, the minister also defended the federal security apparatus.

LeBlanc said last week, "The fact that these two individuals are currently in jail and facing serious criminal charges should give Canadians confidence that the Royal Canadian Mounted Police and its partners did a good job in this case."

Prime Minister Justin Trudeau told reporters on Monday that the federal government takes the internal review of the situation "very seriously."

When asked if the federal government knew more about how the father and son immigrated to Canada, Trudeau said he would not comment further as the government’s investigation is ongoing.
