It's easy to understand when most popular streaming services here are foreign owned and have created a terrible image for themselves by producing barely any tax revenue for the country.
Well doesn’t that say more about the inability of the country to produce its own tech environment where their own citizens prefer media produced by foreign companies?
It's a free market. Of course, the US will have a lot more companies coming into Canada than the other way around in tech. It has 10x the population and massive amount of capital. So, yes, you are correct Canada is not competitive against the USA in that matter.
Though, i'd argue it has nothing to do with the fact that they should be taxed appropriately in Canada. It replaces revenue from TV distribution that was appropriately taxed. Similar discussion to whether we should tax robots labour i think.
Also, I think countries have the right to promote their own culture. That might be hard to see from the POV of the country who's culture is slowly boulderizing that of the rest of the planet.
