I sat down last night and did some limited research into this, here's the results.
From Transporting Dangerous Goods By Truck published by the Canadian Trucking Alliance, 3rd printing revised as of September 2002.
Definitions
MoC - Means of Containment a container or packaging, or any part of a means of transport that is or may be used to contain goods.
Small MoC has a water capacity less than or equal to 450 litres.
Placard a safety mark that is visible and legible, made of a durable and weather-resistant material, and is of a specified colour. Its shape is a square on point with each side measuring at lest 250 mm (10 in) in length with a line running 12.5 mm inside the edge.
Label a safety mark that is visible and legible, made of a durable and weather-resistant material, and is of a specified colour. Its shape is a square on point with each side measuring at lest 100 mm (4 in) in length with a line running 5 mm inside the edge.
Carrier a person (an individual, corporation, or any other person carrying on a business) who, whether or not for hire or reward, has possession of goods while they are in transport.
ERAP Emergency Response Assistance Plan, explains actions to take or avoid in event of spill.
Chapter 14 Special Requirements
14.12 The documentation, placarding and training requirements do not apply to UN1001, UN1002, UN1006, UN1060, UN1072, and UN1978 if the dangerous goods:
· Are in no more than 5 small MoC;
· Gross mass is less than 500 kg; and
· The labels can be seen from outside the vehicle
From Schedule 1
UN Number UN1002

Special Provision #42
Part 3, Documentation, the placarding requirements in Part 4,Dangerous Goods Safety Marks, and part 6, Training, do not apply to transporting these dangerous goods on a road vehicle solely on land if
(a) the dangerous goods are contained in no more than 5 small means of containment;
(b) the dangerous goods have a gross mass less than or equal to 500 kg; and
(c) the labels displayed on the means of containment can be seen from outside the road vehicle.
UN1001, UN1002, UN1006, UN1060, UN1072, UN1978
Limited Quantities Exemption
Limited Quantities are dangerous goods that are shipped in small packages, and are therefore considered less dangerous. A quantity of dangerous goods is considered to be a limited quantity if:
· the innermost containers do not exceed the quantity specified in column 6 of schedule 1
· the weight of each small MoC and its contents do not exceed 30 kg.
Limited Quantities are exempt from most of the requirements except for labeling.
Label for non-flammable, non-toxic gas is green background, class 2, with bottle on top half of label.
So, in closing and this is only my opinion!!!!!
You are okay transporting 5 or less of your own tanks, but maybe for CYA aspect you should get a class 2 label on your tanks and transport them in open view (not car trunk). I'm attaching the label as example only, not official one.
And you can always go to
www.tc.gc.ca and look for yourself.
Have fun diving, let's not panic yet on 'Scuba Tanks as Dangerous Goods' please.
