You can’t restrict access to parking for anyone who has a legitimate right to park in their own space.
A better motion would be to initiate a “Administration Charge” for issuing parking notices to any owners who park in visitor’s parking.
pass a by-law, put up a large sign that says any owners who park in visitors parking will receive warning notices leading to a Notice to Comply and a fines of up to $550 at the CTTT.
And underneath you put in big, bold letter “Warning Notices carry a mandatory $100 administration fee for each notice that is issued.”
