I notice the BCCOM home page has a notice about mandatory snow tires after Oct 1. The BC Ministry of Transportation says on their website:
"Motorcyclists are not required to use winter tires, as winter tires are not available for most motorcycles. Instead, motorcyclists should use common sense when deciding to drive on BC highways between October 1 and March 31."
