Over the past year, advocates or elected officials in Montreal, Ottawa, Victoria, Baltimore, New York City, Ithaca (NY), Seattle, San Francisco, Glasgow and four cities in Ireland have called for the implementation of supervised injection services. More recently, Toronto’s Medical Officer of Health Dr. David McKeown recommended that the Board of Health start a community consultation process toward establishing supervised injection services within three existing facilities in the city. The Board voted unanimously in favour. As the lead investigators of the TOSCA study (the Toronto and Ottawa Supervised Consumption Assessment), we support Dr. McKeown’s proposal and look forward to the opening of these services in Toronto.
