As far as I am aware there is no easy was into Canada like there is for some of its commonwealth partners.
I would hit up Alaska or Utah, it would be much easier.
Having said that do you have any skills? If so that changes everything.
Oh and in case someone sees Lamps post above the age for Brits, Aussies and Kiwis is 30.
