How do I claim travel insurance which covers medical costs in Canada?

How do I enter insurance premiums which I paid for upfront for 2 years? I'm not covered by provincial health insurance (I'm not a resident, but I'm a resident for tax purposes). I purchased travel insurance which covers me for medical while in Canada but I bought 2x 1 year policies. Can I claim 1 year now and the other one next year, or do I claim both now?
