As a U.S. citizen attending school in Canada, you need to report your Canada income on your U.S. tax return; you will have to "convert" the T4 entries into $US .
(Unfortunately, we are not qualified or permitted to offer advice on your Canada tax filing requirements).

The IRS also lists the following resources for obtaining an exchange rate:
