American and Canadian culture is a lot more similar, than Canadian and most other cultures -- denying that is pretty silly, even with the current issues ongoing.
The amount, and quality, of the content from other sources is lower than from the USA. I think I mentioned in the earlier post that it's a matter of accepting a diminished quality of life / standard of living -- a reduction in the quality / variety is just that, even if there are 'some' replacement options around.
Subtitled shows aren't the same as hearing your native language spoken in media. It's one reason immigrant parents are often very eager to get media from their home country / in their home language, as it's better to expose their kids to the language/culture of their homeland if they want to maintain some ties.
Endorsing/embracing wide-spread piracy of IP would likely be very bad for Canada on the whole. Piracy to me is 'fine' in moderation and based on subjective individual situations, but if applied broadly to the entire population as a standard, it'd be a negative.
Ideally, Canada would make more content for Canada. But I don't think we realistically have the market size for that.
