On May 20, 2011, La Presse revealed that Rue Frontenac is being sued by Montreal-based Dar al-Iman school. The reasons behind the suit were not mentioned in the article. It is more than likely a libel suit.
Rue Frontenac has published two articles about Dar al-Iman school and its Principal, Lazhar Aissaoui. Both were written by Vincent Larouche and released on November 25, 2010 (PdeB English translation) and January 20, 2011 ( PdeB English translation ).
The Muslim Association of Canada's (MAC) own publications identify the school as a "MAC institution". From 2002 to 2010, the documents submitted by MAC to the Canada Revenue Agency identify Lazhar Aissaoui as a member of the organization's board of directors. From 2007 to 2010, he is specifically identified as the organization's treasurer.
