I read the two announcements to mean there was a separate agreement with Bell Media for some content, which may cost extra, above and beyond the HBO Canada agreement. Canadians will be required to subscribe to a BDU plus TMN to get most of the content. That's not much different than in the US.
I believe the quote below applies to the content for which Amazon acquired US rights. That means it won't be available on Amazon Prime in Canada, which dilutes the value of Amazon Prime to Canadians. I also don't see how Bell is planning to exploit the content. If it's with a future Bell Media streaming service, that will be another added cost to Canadians. In the meantime, it will be unavailable, except on DVD. If Bell Media decides to make the content available only via an HBO Canada or BDU subscription, that means Canadians will need to pay about 10 times as much as US Amazon Prime customers.
Separate and distinct from the HBO Canada deal, Bell Media has exclusively acquired, for future exploitation, the national multi-platform rights, including SVOD, for the entire off-air library of HBO's iconic programming catalogue. The acquisition represents more than 850 hours of past scripted programming alone, as well as hundreds of hours of HBO movies, documentaries, and stand-up and music specials.
In any case, it still emphasizes how Canadian media companies, such as Bell Media, are locking up content that is available on services such as Netflix or Amazon Prime in other countries. If anyone has any issue with the lack of content on Netflix Canada or the fact that Amazon Prime is missing the video service in Canada, this is why.
