MONTREAL -- Someone walking by <a href="http://www.addingtonhouse.com/" target="_blank">Addington House</a> in Notre-Dame-de-Grace would likely miss it. Sitting on a quiet residential street corner, it looks like any other home on the block, concealing its purpose as a centre for the treatment of addiction. It has been in its current location since 2002, and has occupied two other NDG addresses during its 25-year history. But after residents complained to the City of Montreal, it may have to find a new address. "The city has advised us there have been complaints from neighbours," said George Goldberger, the centre's executive director. <blockquote><strong>"The city is asking us to relocate."</strong></blockquote> But relocation isn't going to be easy. The house needs to occupy a property zoned institutional in areas that are residential, as much of its strategy involves treating people in a familiar environment. Addington House is a non-profit that charges $21,000 for a three-month stay. "It's a homey type of atmosphere, it doesn't look like a hospital or an institution," Goldberger said. Yet recent efforts to find a new home haven't been encouraging. Addington House recently held an open house on Montclair Street when it was trying to move into a home there. Its potential neighbours were nonplussed. "My neighbour over there is not happy at all. Nobody is," said Maria Luciani, who would have been a next-door neighbour. "My [property] evaluation is going down at the end. No. I don't want it. I'm sorry." Mischa Phillips lives near the house's current site. She said she doesn't have a problem with it being nearby, "people need help," she said. City councillors who deal with NDG did not return calls seeking comment.
