After trying the yellow page vendors listed under 'Propane' with no
success, I think I found some good ones under 'Recreational Vehicles -
Sales & Service'.  Maybe it's just Quebec...... but it seems all the
propane vendors around here just do BBQ tanks and 'aren't allowed' to do
other tanks.

Anyways, stores are closed for the evening but I will try the RV shops in
the morning and expect to locate something.  Thanks for the replies
everyone.  It seems a tank is good for a good couples weeks at least.
Cool!
