Immigration Minister Marco Miller said he plans to consider whether Canadian citizenship should be revoked from the man accused of plotting a terrorist attack in Toronto.

Ahmed Fouad Mustafa Al-Deedi, 62, and his son Mustafa Al-Deedi, 26, were arrested in Richmond Hill, Ontario, and face nine terrorism charges including conspiracy to commit murder on behalf of the Islamic State in Iraq and Syria.

When the Royal Canadian Mounted Police announced the charges on July 31, they stated that the two men "were in the advanced stages of planning a serious and violent attack in Toronto."

The elder Al-Deedi, a Canadian citizen, was also charged with aggravated assault abroad.

In a press conference held in Church Point, Nova Scotia, today, Miller said he has tasked his deputy with establishing a timeline of the events that led to his obtaining citizenship.

Under federal legislation, Canada has the ability to revoke a person's citizenship if it was obtained through false information or concealing relevant facts.
