You have no future ... there are too many people that want to teach at universities and when the labor pool us too large for the market, prices, terms and working conditions will be depressed. We're still cranking out PhDs that have no hope of a university position, so I expect your chance of earning a living will drop. I can't comment on employment elsewhere on the continent, but in Pennsylvania (US) there is a severe shortage of AP Physics, AP Chemistry and Calculus teachers. You could easily land a full-time job at a high-school here.
