Abatements are credits back to the purchaser for mistakes made by the developer. You can go direct and complain about this mistake or you can join up with others and have a company negotiate on your behalf. Though developers make alot of mistakes, not all of them can be considered in an abatement as there are many disclosures and representations made in your original agreement of purchase and sale that cover them for these mistakes. Common abatements would be a piller in your bedroom that was not in the floor plan, failing to build certain amenities or not giving enough visitor parking spots. Your best advice is to join a face book website whereby others are talking about it or check out Canadian Condominium Rebates to see if others have made similair complaints
