I think he'll have a great legacy in hindsight. The important policy accomplishments of the NDP while he was leader will hopefully last for generations.
For comparison, what policy accomplishments have the official opposition had in the last ten years, and what accomplishments will they have under a Carney government? The CPC has more than 10× the number of seats the NDP does now, but as a party they have had a lost decade in terms of policy impact whereas the NDP has scored big wins.
The NDP will hopefully have a comeback next election. I would guess they will.
I've thought since Alberta separatism was first mentioned in the oval office that the idea would be to make Alberta be to Canada what Crimea is to Ukraine. The groundwork had been laid and the danger from the US is real. Thankfully, I believe Carney understands how real the US threats are.
How much of this do we see in Alberta this year?
