You've worked with a tertiary hospital. That makes you qualified to apply with the govt. hospitals here then. Regarding the cancellation fees being charged by the agency, ask POEA if that is legal. You have plans to go to Canada, then if ever you'll get lucky to work in the govt. hospital here you'll have an advantage in terms of skills enhancement since the equipments being used are modern. And that private clinic? Maybe the hospital you came from is better equipped. Good luck!
