Not sure if it is the same document but the one you should use looks like this (your photo will be attached to it) - See photo
I never used this document personally to travel within Canada so I can't confirm if it is accepted within the country.
Why don't you apply for a province photo ID or driver's licence? Both of these IDs are accepted for domestic flights and anywhere you need to proof your identity, plus you don't risk losing your RDCD while traveling

You can. I did it from Ontario to Alberta. No problem.
