John Tennett has run afoul of the city's zoning by-laws. All Ontario municipalities are empowered to enact an "official plan" which specifies USES of properties in various zones throughout the municipality. So, some zones are residential use only, some are commercial, some are mixed-use, some are light industrial, some are multi-family dwelling, etc. The plans are drawn up by the municipalities after public meetings at which all citizens and interested parties (builders, industrialists, religious leaders, whatever) are free to speak and make presentations, ultimately an official plan is drawn up and then submitted to the Provincial Government for approval. The plan must meet Provincial planning standards as to minimal green-space requirements, avoidance of "flood plain" building - - i.e. nobody can build in an area adjacent to a river or stream which is likely to be flooded once in a hundred years - - adequate road, school and parkland provisions for every unit of population density, etc.
Both the original Official Plan and the Ontario government planning criteria are drawn by civic planning experts in consultation with all interested stakeholders and approved by the elected representatives of the people. So how this is any more oppressive than any other majority decision in a democratic government is kind of a mystery to me.
When a person purchases a home, his lawyer checks title to the property and also the municipal zoning by-laws to see what are the permitted uses. If a property was being used for a specific purpose prohibited by the zoning by-law, it is protected ("grandfathered") if the use pre-dated the prohibiting by-law. So when the guy buys the house, if his lawyer did due diligence, there should be no doubt in his mind what uses are permitted and what uses are forbidden.
This guy undoubtedly lives in an area where the citizens and their representatives have decided to permit only residential uses. No garages, no glue factories, no dynamite factories, no rail yards, etc. If he doesn't like it, he shouldn't have bought there. He should have known that his neighbours wanted a nice clean street of suburban houses with white picket fences and no central garage with a bunch of jalopies and wrecks waiting to be repaired, welding equipment and paint booths or whatever the guy has in mind. Ever hear of property values? They're not exactly enhanced on a street of $350,000 houses when the house in the middle has three or four cars under repair parked in the drive or out on the street in front.
This guy's attitude seems to be, Fuck the neighbours, I know what I want to do with my place and if it drives down their property values, so be it. The neighbours and the city, OTOH, say Fuck Joe Tennant, we want our neighbourhood the way it was planned by all of us and not the way HE wants it to be. Moreover, he knew the plan when he bought the house.
