The Alberta College of Physicians is concerned that one of Calgary's methadone clinics still hasn't found a new home.

Second Chance Recovery is supposed to be out of its building in Highland Park by the end of the month because the area is not zoned for a medical clinic. The clinic has been looking for another space for months, but is having trouble because other communities don't want it in their area.

Dr. Janet Wright, an assistant registrar with the college, said she has written to the City of Calgary to outline the college's concerns about the forced closure of the clinic — one of two methadone clinics in the city.

She said the closure could mean that up to 500 people will have to be treated by other addiction services in the city, which could lead to waiting lists and many vulnerable people.

"And without the support they get from that clinic, without access to methadone, I mean the very worst-case scenario is that people go back to using substances because they don't have their methadone," said Wright.

Wright said she hasn't received a reply to her letter of concern to the city. She said other addiction centers in Calgary are working on a backup plan to help out in case Second Chance closes.
