The Hells Angels have lost a bid to Canada’s top court to hang onto their old fortified clubhouse at 498 Eastern Ave. in south Riverdale.

The Supreme Court of Canada announced on Thursday that it won’t hear an appeal by the outlaw motorcycle club to hang onto the building, which was seized by the Crown in 2007, amid a series of mass arrests.

The raids were part of an undercover operation that centred around the work of the charter’s former sergeant-at-arms, David (Shakey Dave) Atwell, who is now in a witness protection program.

The converted house had been a social hub of sorts since 1978, when it was bought by the Para-Dice Riders Motorcycle Club.

The Para-Dice Riders were absorbed by the Hells Angels in December 2000.
