Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
You can use your mac, and the free garmin express program to update or change the maps on your Garmin. Depending on what maps came installed, you may be able to change the region to include canada for free. Heres how ( once you have garmin express installed )
If your device shipped with the full north american maps, you can switch to a Canadian map following the page above without cost.
Most likely though, you will either need to purchase a Canada Download or SD card. Id suggest the sd card as its much simpler to use.. You can get the sd card here at a 6$ discount http://amzn.to/29FHk1s
Or, if you opt for the downloaded map version, you will still need a SD card to place the map on.. These steps will help you if you are using the downloaded version instead ( after you purchase the canadian map)
Download and install the map install program, https://www8.garmin.com/support/download_details.jsp?id=3825 Then insert the SD card into your garmin, and then connect your garmin to the mac and then run the map install progam.. it should detect your garmin and then allow you to download the new map directly to the SD card on the garmin.
If you get stuck or run into any issues, let me know.
