TORONTO – The city's medical officer of health is urging Toronto to introduce supervised drug injection sites for intravenous drug users, according to reports.

David McKeown is reportedly poised to release a report Monday which calls on the city to create between three to five facilities providing a safer atmosphere for drug users to inject pre-obtained narcotics under a nurse's supervision in order to curtail overdoses.

McKeown and City Counciloor Joe Cressy, the chair of Toronto's Drug Strategy Implementation Panel will address the media Saturday.

On Saturday, Cressy tweeted that safe injection facilities should be a "top public health priority."

McKeown's report echoes a 2013 Board of Health report and eventual vote which sought provincial funding for a pilot project, but was met with opposition from both Queen's Park and then-mayor Rob Ford.

McKeown will reportedly recommend housing the safe injection sites on the grounds of existing facilities for drug users, including needle-exchange programs.

Vancouver is currently the only Canadian city with a supervised injection site, although a battle over its safety and constitutionality went all the way to the Supreme Court in 2011. Chief Justice Beverly McLachlin said the controversial facility known as Insite offered  "no discernible negative impact on the public safety and health objectives of Canada."
