BC Ferries have always had confusing restrictions on camping stove fuels. I recall having to surrender our white gas at Port Hardy prior to boarding for Prince Rupert that resulted in some some frantic efforts to obtain fuel on arrival in Haida Gwaii. On subsequent trips to Haida Gwaii this wasn’t a problem.
Regarding the present ban on transporting butane canisters (that I assume would also apply to small propane canisters) this is less of a problem on an outgoing trip when one can pick up canisters on the way to Vancouver Island or Haida Gwaii destinations but presents more of a problem with partially depleted canisters. I guess that we will have to be wasteful and void the canister and then punch holes in it to prove that we are not carrying butane on our return journey.
Speaking of losing reservations I found out the hard way that if you have a reservation for an over height vehicle and turn up under height the reservation is void. This resulted in a lost half day waiting for the next available ferry. It seemed that my offer to strap my passenger on the roof to comply to the over height catergory wasn’t acceptable and was not appreciated.
