Yeah, like the good folk have said, as a low timer it's a bad idea going to Canada for helicopter work. Hell, its gonna be bad enough for guys with 2000 hours, let alone 100+ hours. Since you have your Canadian CPL, you must know how ti al works there. As a low timer, you would only get a job as a hangar rat. Cleaning machines and all sorts of other jobs, all for a very low wage. After you prove yourself, maybe summer 2010, they would let you do maintenance runs and occasional ferry flight. Canada is one of the hardest places to start in the industry as a low time pilot.
Dont waste the student visa this year, unless you wanna escape the crashing emerald isle for other work. In the past Iw ould normally tell most people not to go to Canada until they had between 700-1000 hours. Now, its just gone bad. Very bad!
Since you have a CPL now, you cant go the American route and work there either. So, not sure what the best route would be at this point. Maybe consider doing the JAA and getting an IR to head to the North Sea?? Who knows at this stage. Work around the world is drying up, and its only gonna get worse. What we need to do is get out there and find a way to drive up the price of oil - then we will be in good hands again!!!
Good luck!
