A police-involved shooting in Burnaby has forced the closure of a major commuting corridor.

Hastings Street is blocked off by RCMP cruisers at the MacDonald intersection.

That's where a man allegedly holding a knife was shot shortly after one this morning.

Police at the scene are not talking, but less than two metres from the corner a yellow tarp covers what's believed to be the knife wielded by the man... who's in hospital.

His condition is not known.

The Independent Investigations Office has assumed control of the investigation.

No word yet on when the yellow tape will be removed, so traffic can flow along the usually busy Hastings corridor. 

The only sign of movement right now is a raccoon scrounging for food as investigators take pictures and measurements.
