Hey Benoss...
To get a job flying floats in Canada you will need a work visa and a Canadian CPL - which means doing their flight test and written exam - budget $2,000 for that.
A float endorsement will cost you another $2,000 or so.
If you are under 31, you can obtain a one year working holiday visa without too much hassel.
To get a job - you will need 1000 float hours for most places.
I was lucky and scored a seat with 250 hours. With zero float time, forget it...
Good luck! The flying in awesome!
