BC Ferries says the final round trip sailing on major routes between Vancouver Island and Vancouver are cancelled Monday night because of winter conditions.

The corporation says due to expected deterioration of weather conditions and snow, the last two sailings arriving and departing Swartz Bay, Duke Point and Departure Bay.

For the Swartz Bay-Tsawwassen, the 7 p.m. and 9 p.m. sailings have been dropped, along with the 8:15 p.m. and 10:45 p.m. sailings on the Duke Point-Tsawwassen route.

The final sailing from Departure Bay to Horseshoe Bay is at 5:55 p.m. and the last service coming to Departure Bay from Horseshoe Bay is 6:35 p.m.

The notice says the safety of its passengers and crew is the corporations’ top priority and expects to have service resume Tuesday morning.

Environment Canada’s updated snowfall warning for Greater Victoria and east Vancouver Island forecasts another 15 to 25 centimetres of snow, with heaviest snowfalls expected Monday night.
