After his third prison term, Miner moved to the province of British Columbia in Canada, where he adopted the pseudonym George Edwards and is believed to have staged British Columbia's first-ever train robbery on September 10, 1904 at Silverdale about 35 km east of Vancouver, just west of Mission City. It is often claimed that Miner was the robber, but neither he nor his accomplices were ever tied conclusively to the Silverdale heist. It is also widely reported that Silverdale's train robbery was the first in Canada, but Peter Grauer's definitive study ("Interred With Their Bones", 2005) cites a train robbery in Port Credit, Ontario 30 years prior as the first.
