The chairman of the Canadian Anti-Hate Network wants to see the RCMP and Defence Department treat the disappearance of a Manitoba army reservist accused of harbouring ties to neo-Nazis treated with more urgency.

Bernie Farber says if Master Cpl. Patrik Mathews had been suspected of links to the Islamic State group instead of neo-Nazis, the case would have been resolved in 15 minutes.

Mathews disappeared at the end of August as he was being fast-tracked out of the military for his alleged links to a right-wing extremist group. His truck was later found abandoned near the Canada-U.S. border.

RCMP previously seized a number of weapons from a house in Beausejour, about 60 kilometres east of Winnipeg, where Mathews lived.

"He seemed to slip right through their fingers and he's — poof — gone," Farber said Monday, adding if Mathews had been suspected of links to the Islamic State group instead of neo-Nazis, "I think this would have been resolved in the space of 15 minutes."

RCMP spokesman Sgt. Paul Manaigre says police are continuing their search in Canada and have been in touch with U.S. counterparts in the event the 26-year-old crossed the border.

Manaigre would not comment on any investigation into Mathews, but noted police have not issued an arrest warrant and that his disappearance is being treated like any other missing-persons case.

"He's not wanted by the RCMP right now, he's missing," Manaigre said. "Our American counterparts obviously are very aware of what we are doing and we've also provided them with information."
