Single Room Occupancy hotels on Granville Street are a failed experiment - that’s the word from the Hospitality Vancouver Association after a man was stabbed to death on Monday. The HVA says the so-called SROs are dangerous and unstable and the group is again calling for the 300 low cost rental units to be permanently closed. A man died in hospital after being stabbed on Granville at Helmcken - no arrests have been made.
