Hourly requirements for seaplane operations is almost always done single pilot with the exception of twin otter. Minimum requirements for some of the larger companies are no less that 2500hrs with 1000hrs PIC on type. Many fresh CPL ME IR pilots will get jobs on the ramp or in distpatch for 12-16months if lucky you can snag a 172 job with skydivers or tours. Also there is alot of light twin work in the north that has metro's, twin otters, king airs, navajo's all requiring minimum 500hrs. As stated before their are alot of fresh pilots in Canada and still a slight shortage of jobs. The market is however expanding with the likes of Air Canada Express and other regional carriers and the market is expected to open up in the next few years.
Best of luck
