Sorry, I should have made it clear --  I've used MSR canisters with my JetBoil with no trouble at all.

The JetBoil (which I own) shares a very common stove--canister connection with many other stoves, called a Lindal valve.  Examples of other stoves with this valve include the MSR line, Brunton, SnowPeak, etc.   You should have no trouble finding fuel in almost any store that sells equipment to campers, mountaineers, etc.  For example, Mountain Equipment Co-Op (the Canadian version of REI) sells a full line of Lindal valve canisters.

Most will work - the trick to their smaller one is just that it fits into the container - the bigger ones will not.  This assures them a continous revenue stream beyond the inital sale.

Standard connection.  All Primus iso fuel containers certainly work.

BTW my experience with the Jet boil was very favorable - very, very low fuel consumption - < 1/2 a container in a week of daily use at 2 meals a day.

Ground ship only I believe you can send it by the US Postal Service leave plenty of time for it to get there.
Snow Peak Giga Power canisters will work if you can find them up there

How about shipping your fuel to an outfitter or local store and picking it up when you start your trip?  Maybe you could find someone sympathetic to your cause?

Yada-yada -

I have DEFINITELY used OTHER fuel sources versus products labelled "Jet Boil" fuel (ie. the hockey puck-sized propane cannister).  I'm talking about their propane model.  You mention 80/20 combo, so I'm wondering if you are using liquid fuel of some sort?  If so, I've not seen that kind of Jet Boil.

IF you're talking propane, I've used somewhat larger cannisters that screw on just fine.  I can't recall the exact name of them but they were pretty generic, allowed more fuel volume, & were less expensive.  

If you can get the name of a couple sporting goods stores anywhere along your route in Canada before you enter the park, you should give them a call.  I KNOW I've seen the larger substitutes up there in various places (probably near Fort Frances or in Atikokan) but I can't recall specifically where.  If you're headed to Atikokan, maybe call Walt's Dry Goods???

If I were you, I'd go straight to the source and ask your question of the people who make the stove..

Going canoeing in Canada with my new jet-boil - - but can't take the fuel cannister on the plane and it's not sold in Canada.   Has anyone used a substitute fuel cannister with these units?  I understand the valve will connect to other 80/20 combo.
