When i was in Canada the magic number was 600 hrs.
Those were the minimums for Fire Service work.
Didnt need multi engine or thousands of hours of long line.
Most guys and gals i worked with had been hired with a basic licence, did a mountain course then some forestry work until they got the minimums for fires.
That was 10 years ago though, maybe its a lot harder to fly 206s and Astars now....
