From the Toronto Sun:

The man who has presented himself as the point of contact for the family of Faisal Hussain is a professional activist who has reportedly committed himself to “framing a new narrative of Muslims in Canada” and creating a “national political movement.”

 

Shortly after the Ontario Special Investigations Unit revealed the identity of the Danforth shooter as 29-year-old Faisal Hussain, a news release was sent out to select media attributed to the “Hussain Family”. […]

 

It was provided by Mohammed Hashim, a full-time organizer for the Toronto & York Region Labour Council. Social media accounts belonging to Hashim show him heavily involved in supporting NDP candidates both federally and provincially in Ontario. He’s also described as a driving force behind the National Council of Canadian Muslims.

NCCM is CAIR’s Canadian branch, formerly called, CAIR-Canada.
