I've documented the changes on the TVNT Discord server - it appears they are just updating the logos for the most part. Some graphical elements, such as CFTO's Community Calendar, now CTV Our Community, and the aforementioned promo graphics (chryons and all), were completely redone with new graphics. Their news app was also overhauled too.
Also noted in the TVNT Discord server:
"The roll out is...quite slow. The new CBC standardized logos were quietly introduced in the middle of the Fall 2017 season... and it was only used for internal documents concerning the CBC TV network. Fast forward a year later, the TV network began using it in promos, and the Sports division formally opted in afterwards.
Either way, a new look for the CBC is looong over due. The corp was using the same logo structure for almost two decades now."
Looking at the visual motifs, it appears The National's chyrons are a part of the current CBCNN/local refreshed graphics, so there will not be a refresh anytime soon.
