Could it be a private arrangement between two unit owners/residents? Do you know for certain the direction to change spots came from Council?
My hunch is that is probably the most likely situation. If Council got involved in facilitation that change.... now, that would be interesting and in my opinion an overreach, assuming that your strata plan has parking spots noted as 'limited common property' (LCP) . Any LCP would be noted directly on the Strata Plan and can NOT be changed at will by Council - it would need to go to a vote by ownership at an AGM or SGM for a change.
Although Council has a duty and a responsibility to ownership to uphold bylaws and whatnot especially with respect to human rights issues (i.e., smoking and accessibility), it is a different beast IF parking spots are noted as 'LCP'. A unit owner trying to use accessibility as a human rights issue in this instance does not override the powers of Council in what they can and can not do, which is set out in legislation.
However, it isn't unusual for parking spots in some (usually older) stratas to be common property, so that strata has the authority and jurisdiction to have more leeway to manage them, but if it's truly LCP (i.e., on the strata plan it's assigned to your unit), then that's a different story. Council can NOT change that. And if they were to make an arrangement or help facilitate an arrangement by a private owner..... if I had been on Council I would have urged my fellow Council members to stay the hell away from that and remove myself from that discussion, and have that decision minuted.
The authority of what Council should and should not be doing is very clearly outlined. This should actually work to their advantage when dealing with douchers like Yaniv. In my opinion.
Interesting....
