The simple answer might be to paint over the disabled parking markings and let those no longer able to park pursue the EC.
However, I think you should take this as an opportunity to work out what the community wants and needs, plus your legal obligations.
Propose in a motion to the to the EC that it agrees to “consolidate” common property, as per the original strata plan, plus any subsequent adjustments that have been registered as by-laws.
Then propose another motion to identify some “loading zones” and establish the length of time they may be used (you may need a by-law for this).
Also, find a space for disabled visitor parking. Define the length of time visitors are allowed to park (again, a by-law may be required).
Meanwhile, find out form councilwhat your legal oblif=gatiosn are when it comes to disabled parking.
Then, further down the track, issue Notices to Comply to anyone who parks in the loading zone and/or the disabled visitor parking without a permit and/or for too long.
