From http://greyhound.ca/en/company/potential_service_disruption.shtml
The affected region includes Greyhound service within the provinces of British Columbia, Alberta, Saskatchewan, and Manitoba. This would also affect service between Winnipeg and Toronto, Winnipeg and Ottawa. However, service on Vancouver Island will still continue to operate with Island Coach Lines. Customers outside of the affected region would see no change in service, whether it’s for passenger service or parcel delivery. It is business as usual as that part of the network is fully operational.
So it shouldn't affect KW <-> Toronto
