Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
"Generally speaking", you MAY be able to get Canada maps on the device, but there may be a couple of "precautions" to check FIRST.
So may I ask if you can grab the unit and:
1) Find the FULL Model Name & Number of the device you are working with?
2) The AGE of the device?
3) Do you have a USB cable - for connecting the device to a computer (you'll need a computer too)?
