I'm all for women's right to choose. How would we make money, I think we'd essentially be funding US medical treatments, which I'm ethically fine with, but would prefer to have my taxes go towards things for Canadians.
My understanding is that we can't have a private system along side the public system without "funding" the private system by WTO rules. Besides the fact that running a private system beside a public system is parasitic (i.e. we are assuming an infinite supply of doctors and nurses).
I think we should probably focus on paying our existing nurses and doctors better, and getting our hospitals back in working order.
An American can get an abortion now at the existing clinics in Canada if they want, and if there is availability, they just have to pay for the procedure because they wouldn't be covered under the provincial health plan.
