If your device is more than five years old, your system may need an upgrade

Over the next two years, the computing industry will eliminate certain security protocols that are more than 10 years old. The Canada Revenue Agency (CRA) regularly updates its secure online services to ensure they feature the highest security standard, which is Transport Layer Security (TLS) 1.2. The CRA encourages you to upgrade to TLS 1.2 so that your system is as secure as possible. For information on whether or not you may need to upgrade, go to Setting up your device to use CRA online services.
