Employers are required to pay professional pilots at least the minimum wage. This was checked some years ago with Manpower or whatever the feds call it now. The response indicated that there is no actual federal minimum wage so the Feds use the minimum wage in each province or territory. eg, if you are employed as a jump pilot in Ontario your employer is required to pay you at least the Ontario minimum wage.
Competent and ethical drop zones comply with the law. Whether they pay by the hour or by the load their pay does work out to meet the minimum wage standard. There are usually a few perks such as a free beer at the end of the day, free meals at the drop zone cafe or even a free jump if you are nuts enough.
There are rumoured to be some drop zone operators who pay below the minimum, do not pay their pilots at all or expect pilots to pay them to fly. Such operators are breaking the law and by extension probably have invalidated their insurance. Also it is a fair and reasonable assumption that if an operator is breaking the law in one area (pay) it is almost certainly doing the same in other areas such as maintenance, flying overloaded, ignoring safe operating procedures, etc. Stay well clear of such scumbags!
Jump flying is a great way to build up time and gain real experience as against the pseudo-experience of circuit jockeys (instructors). You will find that skydivers are reluctant to trust a new pilot but once they gain confidence in your ability they really look after you. Skydivers have great parties. Once you are accepted, away you go!
