No, because that would not be in anyone’s interest, and especially not in the interest of the online platforms.
Some people make this threat by arguing that Canadian content would be artificially recommended rather than offered by popularity and, being unpopular, people wouldn’t watch it, so they would lose points.
The recommendation system could very well suggest popular Canadian content, because it exists in abundance! But more importantly, just because content is not popular doesn’t mean it can’t become popular through recommendations. Recommendation mechanisms allow emerging creators to gain popularity. If the creators of this content are discovered and appreciated in Canada, this will increase their score in the recommendation system and expand their notoriety internationally.
