Article 5 sounds great until a conflict escalates and Canadians have to go and die in a war.
The whole thing about trust and narrative is very one sided. Every news and information source from the opposite side has been silenced, deplatformed, banned etc. Yeah yeah, I know, it's all Russian lying propaganda. Ukraine - 100% truth, Russia - 100% lies.
The entire conflict was all about resources and influence. Ukraine is a country that has oil, gas, fertile soil, metals and minerals etc. They couldn't be allowed to stay under Russian influence. This was a conflict decades in the making.
