Western alienation is real, and is to a great degree justified. Note: I'm not a separatist or anything, I'm not partisan (no Canadian party represents my views), I just live in the prairies and have a front-seat view.
The issues that cause this #alienation are longstanding. This didn't just arise because of Trudeau, or even just because of the last generation of governments. It goes back further than that. The west sees many reasons to believe (rightly or wrongly) that they get short shrift from the federal #government.
One recent example: Ottawa saw a threat to Canadian auto workers (southern Ontario only, natch) in desirable Chinese electric vehicles that have taken much of the world by storm. So Ottawa slapped a 100% #tariff on Chinese electric vehicles. It's not only the US that can play stupid games.
The #stupid prize they won is a 100% #tariff by China on the import of Canadian canola oil and #canola meal. This is a hugely important cash crop all across the prairies, and China represented farmers' biggest #market. This tariff has decimated that income. Farmers are hurting because of it, and the prairie provinces' economies are still significantly tied to #agriculture.
Ottawa basically doesn't care. Have to protect Ontario jobs. Eastern farmers aren't affected. Why do anything to help prairie #farmers and provinces?
Note this is just one example. There are many, in all areas of society, politics, and economics.
