Different FOI's will have different opinions. Your business can fly a director on a private aircraft under a private operation for the purpose of conducting trade (a sales meeting for example), yet you cannot fly "goods" for trade...
You almost need a full time lawyer to conduct any form of aviation, private, business or commercial. That alone is the most common reason why most people I have spoken to will not even try, it simply is to difficult to understand or get a firm answer.
Business Aviation should be thriving in this country, it is a fantastic business tool if you can use it efficiently, unfortunately in most cases CAR 206 prohibits this from happening with absolutely no positive effect on safety.
Realistically does having an AOC make the carriage of fish from A to B any safer than that same operation conducted privately? Nope.
Does it make that operation financially prohibitive? Yes, the cost of compliance would be circa $40k-$50k a year. (chief pilot, aoc issue and costs to maintain this, administration etc.)
It is frustrating because I see so much potential!
