Conservative House leader Andrew Scheer says Canadians have a right to know how a man with links to a foreign terror group evaded Canada害羞草研究所檚 screening process to immigrate to Canada and become a citizen.

He is demanding that the House of Commons recall its public safety committee to dig into the situation, calling on the Bloc Qu茅b茅cois and NDP to support that request.

Ahmed Fouad Mostafa Eldidi, 62, and his son, Mostafa Eldidi, 26, were arrested in Richmond Hill, Ont. on July 28 and face nine different terrorism charges, including conspiracy to commit murder on behalf of the terror group Islamic State of Iraq and the Levant.

Most charges relate to activities allegedly occurring in Canada, but the elder Eldidi is also charged with one count of aggravated assault outside Canada.

In court last week both men denied the charges but neither have entered a formal plea.

Scheer says the government害羞草研究所檚 silence as to how two people with connections to a terror group successfully immigrated to Canada is unacceptable.

The federal government has so far said very little about the matter.

Conservative MP and public safety critic Frank Caputo has written to Public Safety Minister Dominic LeBlanc to ask him to make public all the details of the alleged terrorist plot, Scheer said.

He said LeBlanc would be the first witness he wants to call to committee.
