Disregard..... I found the law on it but it's Quebec law.
Reads like this.....
Possession of a firearm is prohibited on certain premises of designated institutions, on school buses and on public transit, except transportation by taxi. However, if you are the holder of a permit authorizing the possession of a firearm and you exercise an activity permitted by law, an exemption permits you to travel by:
- motor coach
- shuttle
- train
- aircraft
- ferry
This exemption applies if you do not have any other choices but to use these methods of public transportation given your personal situation or the activity that you wish to participate in. An exemption also allows you to use chartered transport when this method of transport is retained exclusively by a group in order to exercise an activity permitted by law, such as hunting or trapping.
