Ah - I misunderstood and thought she had travel history that included UK / Europe.
A study permit is a route she can consider. She will need to show a bank balance of at least $25,000 to cover first year tuition and living expenses. She will also need to make sure that her planned studies in Canada make sense and align to her previous education and work experience (and show a progression in studies). She will still need to show strong ties to her home country to be approved.
If you get married, then you can sponsor her for PR through spousal sponsorship / family class sponsorship which I think is taking around 16 months these days.
