Neighbour wants to access CP via my lot

Not my immediate neighbour, but the next one along is renovating.

He recently bought the premises and decommissioned the a/c unit.

He put a motion to a general meeting to be “allowed to access common property to install pipes relating to a new a/c unit and to access any neighbouring units to access common property if need be”. I told the agent that I doubt the OC has the power to dictate to a lot owner who comes onto their lot (other than in say a flood or fire). Agent replied that even if passed, the renovator will not be able to do anything without the neighbouring units’ consent. I voted against.

I did not consent because I have no idea how troublesome the pipes may be over time and don’t want the neighbour to arrange servicing it at his not my convenience. In short, I do not want to be disturbed when his pipes are serviced or repaired in the case of a major failure that results in flooding my place.

Given in over 3 decades I never received such a request (to access my lot so another lot can install pipes or anything else for that matter), I wonder if the renovator has any legal right to access my lot.

I await a copy of the building plans but suspect either

(a) It is cheaper to install pipes through the CP of neighbouring units than it is to complete the job through the renovator’s unit alone; or

(b) If indeed there are pipes crossing my unit that serviced his now defunct a/c system, then he may want new pipes to service his new a/c unit.

In short: can the renovator demand access to my lot against my wishes?

FYI, I told him “no” every time he asked: 6 times in the last few days.

Any advice is appreciated.
