Mynot, I noticed this portion in the link you provided.
"The proposed new Impact Assessment Act is currently undergoing review by Parliament.
Until the proposed legislation comes into effect, existing laws and interim principles for project reviews will continue to apply to projects under review."
===============================================================
Based on this further link, it looks like a considerable amount of steps need to be taken before this proposed legislation comes into effect.

From what I read, my understanding is that the liberals are still able to approve the EA before Doug Ford steps in.
