Hey,
I used to work for Borek in Canada and Antarctica. Your best bet is the Maldives. You must have a float rating. Apply directly to Maldivian Air Taxi. The website has a contact for the chief pilot last time I looked. I am almost certain you will have to sit right seat for a minimum of 500 hours(6 months) up to to 1000 hours until competency is displayed for float flying, more importantly...landing. I doubt you have a chance flying a "C" registered plane in Canada unless you have all the work permits in order yourself. It is also very unlikely that you could fly for Borek abroad. MAT under the 8Q reg is your best bet. I could be wrong but the chief pilot might be from Oz?
Hope that helps, good luck.
