Welcome to ONE-T

Established exclusively for non-union education sector employees in Ontario, your employee life and health trust (ELHT) will help ensure you and your family continue to have access to meaningful, affordable and sustainable benefits – today and in the future.


Great-West Life Is Now Canada Life

As you may have heard, Great-West Life – the insurer for Life, Health and Dental for your benefits plan under ONE-T – has changed its brand to Canada Life.

It’s important to understand that nothing changes with your benefits or the way you access them. You’ll continue to submit claims the same way, and any insurer tools or resources that you’re currently using (including your GroupNet login and call centre contact info) will stay the same.

All that’s changing is that you’ll see a new logo, and a new look and feel, on the insurer’s website, app, forms and other materials, starting in 2020.

Find out more on the rebranding at canadalife.com. For claims-related questions, call 1-866-800-8086 or visit GroupNet for Plan Members.


We’ve created this website to share information on your trust, and to keep you informed.
