The Globe and Mail reports in its Monday, Feb. 10, edition that economic nationalism has returned to Canada. The Globe's Campbell Clark wonders if it will be a short-term show of defiance aimed at fending off threats of 25-per-cent tariffs? Or a longer-term movement designed to make Canada less dependent on the U.S.? Everyone wants to reduce internal trade barriers. Canadians are calling for boycotts of Netflix and Teslas. The impulse is not new. Canada has embraced economic nationalism many times, going all the way back to Sir John A. Macdonald. Now, Mr. Trump is demanding better trade terms, and having paused his first tariff threat, he nevertheless says he is announcing tariffs Monday on steel and aluminum. However, he is also demanding new border enforcement and threatening "economic force" to make Canada the 51st state. There seems to be a nascent national consensus on building more pipelines to ports, but cutting dependence would also mean passing on proposals to build pipelines to the U.S. Politicians view critical minerals as Canada's main bargaining chip, but future prosperity requires more. Economic nationalism in 2025 must emphasize technology and a national push for intellectual property development.
