Guelph police say three overdoses caused by white fentanyl were reported on Wednesday.

Guelph Mayor Cam Guthrie said in an open letter Monday that he's "done a complete 180-degree turnaround" regarding a supervised consumption site in Guelph and is urging Barrie city council to support the development of a local facility.

The survey, which runs until Dec. 5, aims to gauge how residents feel about supervised consumption and harm reduction services in Guelph.
