If you are looking to get some further details on Canadian drone regulations outside of the CARs Part IX, a great place to look is the newly released Transport Canada Aeronautical Information Manual (TC AIM) MARCH 26, 2020 RPA—REMOTELY PILOTED AIRCRAFT.

This new chapter was added to support operational needs and to be aligned with the new Part IX — Remotely Piloted Aircraft Systems in the CARs.
