I attended the virtual community engagement session last week. Nothing to really report other than that the facilitators seemed to imply that this development may be significantly impacted, perhaps scaled back from the original mixed-use plans because of the pandemic. Worth noting that this came from the coordinator of the session, not the developer itself, and I'm not sure how certain it is.
I expressed my feelings about a mix of uses being crucial to the long-term success of the project -- retail and restaurants may be suffering right now, but they are not going anywhere in the future. If you feel strongly about Northgate, there is another virtual session tomorrow at 12-1pm. They said the link will be the same as the last meeting's, which you can find here.
