Free enterprise-grade protection for all Canadians

Canadian households are under attack by malware and phishing, and family members aren't always equipped with the knowledge they need to avoid malicious content. Heck, even the technically savvy make mistakes from time-to-time.

So where can Canadians look for the same level of protection that large corporations have enjoyed for years without having to worry about their data being sold to advertisers? How about a Canadian non-profit that is dedicated to building a better online Canada?

How it works


Why Canadian Shield is different


How to get started

First, pick your layer

Private: DNS resolution service that keeps your DNS data private from third-parties.

Protected: Includes Private features and adds malware and phishing blocking.

Family: Includes Protected and Private features and blocks pornographic content.

Then, setup your devices

Simply follow the steps below, or visit our advanced configuration guide for more details with screenshots.

You only setup one of our three layers of protection on the network or device. We recommend Protected for most people.

Don't forget to review the privacy policy and terms.

Note that not all routers allow you to change your DNS settings. If you are unable to change your DNS settings on your router, you can still change your DNS settings on each individual device that you want to add privacy and protection to.

Before you proceed we recommend that you write down your existing  DNS settings before you make changes. 

  1. From your browser, enter the IP address you use to access your router’s admin console. Some examples of typical IP addresses include: http://192.168.1.1 and http://192.168.0.1

  2. Enter the router password to access network settings.

  3. Locate the router’s DNS settings.

  4. If you have pre-configured IP addresses, note them down as a backup.  

  5. Enter the Canadian Shield DNS server addresses (IPv4 shown):

    1. For Private, add the following:

      • For IPv4 enter:  149.112.121.10 and 149.112.122.10

      • For IPv6 enter: 2620:10A:80BB::10 and 2620:10A:80BC::10

    2. For Protected, add the following: 

      • For IPv4 enter: 149.112.121.20 and 149.112.122.20
