Legalization of cannabis production, sale, and use in Canada in Fall 2018 provides the context for the largest wastewater-based epidemiology (WBE) pilot test conducted to date in North America (8.4 million people) and the first by a national statistical agency.  Key findings from the first 12 months of collection are presented for Cannabis and other recreational drugs.  The study provides baseline data on several potentially important facets of drug use in Canada, but also raises challenging questions on how best to apply such data as input to official economic and social statistics.  Areas of priority research needed to improve the applicability of WBE techniques as input to national statistics are outlined, as are Statistics Canada’s thoughts on how to extend the value of WBE to other phenomena.
