"Canada is in the midst of a devastating overdose crisis that has been further exacerbated by the COVID-19 pandemic and, in particular, the subsequent increased toxicity of the drug supply . Between January 2016 and June 2022, close to 33,000 people died from an overdose in Canada, with the provinces of British Columbia, Ontario, and Alberta accounting for 88% of those deaths . Fentanyl, and to a lesser extent fentanyl analogues, have contributed to a sharp rise in the toxicity of the unregulated drug supply and fatal overdoses . Between January and June 2022, fentanyl was detected in 76% of overdose deaths in Canada . In Ontario, fentanyl is involved in 88% of fatal overdoses . In Toronto, this number rises to 93% ."
