Where are you at?
In a whole world of pain.
Since the original extensions were not documented and bylaws passed, a lot of this has passed to OC responsibility.
I can go on about the various omissions.
I think the strata is in this situation because they tried to do the legals on the cheap and not consult lawyers.
I would suggest to get a lawyer to look at the history and paperwork to determine who is responsible for what.
You need an impartial arbitrator, as I can see that it’s going to be a standoff between owners.
And unfortunately all owners will be paying for the past sins.
