If a green banner displays at the top of the page, the browser successfully supports mapping.

Check Your Connection Speed 

The map may be slow to load or may time out due to a slow connection speed.   To test your internet speed:

  1. Google Internet speed test.
  2. From the top result, select Run Speed Test. 

The Internet Speed Test window should report that your connection is fast. If it is too slow, it will not be able to load a map.

Check Your Firewall  

  1. To check your firewall, copy and paste this link into your browser’s address bar: https://www.emapviewerprod.ca/ 

A sign in window should display. (You do not need to sign in)

If an error or blank page displays, you will need to change your firewall settings to allow https://www.emapviewerprod.ca/ and http://www.emapviewertraining.ca.

You may need to contact your system administrator to help change firewall settings.
