I thought after the weekend's diving in BC, it would be good to post this. I had a very pleasant experience with declaring tanks (marked as Nitrox tanks) on the BC Ferries.
They DO accept Nitrox tanks and even their web site declares it so.. see BC Ferries - British Columbia Ferry Services Inc. - Experience the Difference and read the "Scuba Tanks" section on "Enriched Air" (I would print out this page, highlight the Enriched Air portions and take it with you!)
The Ferry officials were so impressed by the forms, they put me up front and I was first on and first off the ferry! This was from Horseshoe Bay to Langdale and back!!
BEFORE you get to the Ferry terminal, download and fill out the Dangerous Goods Shipping form with the following information:

For Air AND Nitrox tanks (Yes, declare Nitrox up to 40% as Air):
Proper Shipping Name: Compressed Air
Class: 2.2
Sub Class: (Leave blank)
UN#: 1002
Packing Group: (Leave Blank)
Flash Point: (Leave Blank)
Marine Pollutant: (Leave Blank)
QTY: 4 CYL (Your Cylinder count.. mine was 4)
Gross/Net Mass: (See below on how to calculate - they are VERY impressed when you have this)
For 50% to 100% O2 Deco Gas, declare as Oxygen:
(Everything is the same as air, except name and UN#)
Proper Shipping Name: Oxygen Compressed
UN#: 1072
How To Calculate Gross weight and Net Gas weight:
Air and Oxygen roughly weights 35.40 grams per cubic foot.
Weigh your tanks when they are full, thats the Gross weight and then calculate the weight of the air, that is net weight (per tank)
For example:
My worthington HP100 steel full of air = 46.52lb = 21.1Kg (Gross)
The compressed air for 100cft = 100 x 35.40g = 3,540g = 3.54Kg (Net)
I had four tanks so Gross weight and Net weight times four and rounded off to closest digit:
Gross/Net Mass = 84kg/14kg
