I'm a noob when it comes to all of this as well. My understanding is that they should ideally fix the issues outlined in the PDI before we move in (they've had quite a lot of time!), but during occupancy period, the builder is entitled to enter our unit at any time to fix things...
@stevenp my island countertop is missing as well, but I noticed someone else had the same issue and it was installed before they moved in. Hopefully it'll be there when I go next week!
Looks like the 3 of us all have January 13 occupancy
... I just finished meeting with my lawyer today. Super excited!
