WASHINGTON — A former top U.S. Drug Enforcement Administration official has come forward with explosive allegations that Canadian authorities obstructed a high-level DEA investigation into a 42-kilogram carfentanil seizure tied to a 2018 mass shooting in Toronto and, according to senior U.S. investigators, potentially linked to Pakistani threat networks and Chinese chemical precursor suppliers.
The DEA learned, after 29-year-old Faisal Hussain’s shooting rampage on Danforth Avenue—which left two people dead and thirteen more wounded—that his brother and a network with Pakistani links were connected to a historic seizure of carfentanil, a synthetic opioid 100 times more potent than fentanyl, in September 2017. The drugs were discovered in a suburban Pickering home, alongside specialized equipment consistent with a transnational trafficking operation.
