Canon don’t make money from people who stick with gear they have.
This was exactly my point. Most people do stick with the gear they have and then don't use what they have.
You said that Canon needs to move customers to mirrorless. My question to you is why or how? The real money spent on ILC cameras is in the accessories, not the camera body. I have a Canon DSLR, but just one. I also have about 40 lenses. My "L" glass could be used on an R body right now. So why don't I go buy an "R" body? Because the R body isn't going to produce photos that are enough better to justify it. My point is, DSLR or mirrorless, there is no earth shattering difference or reason to switch. Look at Sony: 14% market share and they've been on the mirrorless road for a long time.
Mirrorless is not the industry savior. There really is not anything special about it vs a DSLR. Canon just needs to do whatever Canon does to keep making money. I think (fantasy) that ILC sales will continue to decline. It isn't because of the cameras. It is a pop culture shift in what people value and how that is expressed. People now have their phone, TV, internet, camera and the Library of Congress in their back pocket. They don't want a backpack full of stuff. Photos? All on the phone and they are happy with low res tiny photos.
I've done a couple of recent shoots. Neither client cares about the hi res large file images I can provide. "Instagram and Facebook size is good enough."
Constantly trying to win the mega-pixel war doesn't help either. Why would a person purchase a 100mp camera (non-pro) that isn't going to use the photos for anything other than the web?
I think a large number of people probably see ILC's as too expensive, too bulky, too complicated, and a waste of time and money. Of course, I think the same thing about Bass Boats.
When's the last time anyone has seen an encyclopedia salesman? Extinct, aren't they?
