Yes. The danger is that Canada is not an essential market. It's a good market for the major tech platforms—however you describe them—but it's not critical. It's perfectly possible for platforms to simply not serve the Canadian market.
It's a bit of a danger with the really big platforms, such as Netflix, for instance, in the streaming sector, but I think it's really critical with the smaller and innovative services that are coming along. If the price of entry to the Canadian market becomes too steep for new services or for minority services, Canadians will suffer, because those will not align and act in Canada. If they're not available in Canada, then Canadians are losing out.
The primary purpose of the Internet is to be demand-driven and not supply-driven. The Canadian system is designed to be supply-driven rather than demand-driven. When that's applied in various sectors, one can see that Canada can lose out—and individual Canadians lose—from the lack of access to new products and innovation.
