If you're talking about the SiriusXM Canada app with the free 1 month trial, then yes, you can - there's no reason you could not.
Of course, in order to listen to radio through this app, it will use data. If you bust your monthly data plan, you will have to pay for that over-usage, just like any other app.
How much data it will use depends on how much you're going to listen to XM...
