Invoked new legislative powers how? The federal government can’t simply demand the provinces do anything.
You can’t invent federal levers out of thin air! https://www.thestar.com/politics/federal/2020/10/27/once-seen-as-a-star-in-justin-trudeaus-government-patty-hajdu-is-now-the-incredible-shrinking-minister.html

Further to this, I’m not sure how useful more robust federal models would have been. We’re a big country with lots of separate outbreaks, and one federal model isn’t all that helpful – especially because healthcare delivery is provincial jurisdiction.

And even if they had more robust models, what was Hajdu supposed to do with that information? Federal health delivery is only for the Canadian Forces, First Nations and Inuit, and that’s not even under her department any longer.

Blaming Hajdu may feel satisfying, but everyone should be looking to premiers and provincial health ministers. But once again, they’re getting a pass because of the deliberate obfuscation of jurisdiction in this pandemic.
