Canadian Cellular Towers Map

This is may be a useful website for those deciding where to rent or buy a house or apartment, or where to send their children to school.
When you click on this website, it automatically produces a map of the city where your internet connection is. This map has colour-coded icons showing cell phone antenna locations and who owns them.
To find out where the closest antenna is to your home, business or school, enter the address in the search bar.  The website will display the closest antenna to that address, and then if you can click on the icon of the antenna itself; and it will give you the carrier frequency of that antenna, as well as the name of the company that owns it.
