I just had a "duh!" moment on another thread (thank you Robert!).
Rollei films are "produced" by Maco, whatever that means, but what it REALLY means is that to find out who sells them in your country, you need to find a Maco reseller.
And so Maco's site has an entire page devoted to this on their site:

I've contacted one in Canada, and found that he has the fabulous Retro 100 and 400, i.e. the APX ones.
So if you're crying for the loss of Agfa films, stop wasting your precious bodily fluids, and call (or email) instead your local Maco dude.
