No!
I'd certainly go over in your leave and make some contacts and make yourself available in the next year's leave to relieve timex pilots over the fire season, but don't leave that secure job just yet. You will need to find a company that's willing to put you through the other training BS, like WHMIS, Dangerous goods, etc., but it's worth the effort if you do it properly. I would probably leave it until you are between jobs.
There are loads of your countrymen working there - try talking to them first, if you can find them.
Good luck!
