The RCMP has charged the former executive director and CFO of SISO with fraud.
The Mounties allege that Morteza Jafarpour and Ahmed Salama used the registered charitable organization as a vehicle to defraud the federal government of more than 4-million dollars.
RCMP and Hamilton police say their investigation uncovered a sophisticated series of schemes spanning several years.
Investigators say they included falsifying invoices, payroll and employee information.
The 52-year-old Jafarpour and the 39-year-old Salama have been charged with knowingly using forged documents, fraud over 5-thousand dollars, theft over 5-thousand, and conspiracy to commit fraud.
SISO was funded primarily by Citizenship and Immigration Canada and had several offices in Hamilton, providing settlement assistance and other services to newcomers to Canada.
SISO closed its doors following its bankruptcy in January 2011.
