..."but the Conservatives have used this issue in recent years to accuse their rivals of planning to hit taxpayers for extra revenue." And the Liberals and - until now - the NDP have followed the same line.

Except, if the world of digital disruption continues, it will not be generating extra revenue over time, it will be replacing revenue that is displaced by new modes of service.

I cannot understand the logic of why a company that is providing a service (or product) to Canadians would not be subject to GST/HST. The critical point is that the consumer is within our national borders and the logic of a value added tax is the consumer pays (and company collects and remits).
