FREDERICTON — New Brunswick's cannabis retailer is laying off staff, saying it has a better understanding of "operational needs" three months after the historic legalization of recreational marijuana.

Cannabis NB said most of the layoffs involved people with seasonal contracts, but some are part-time or full-time employees.

Spokeswoman Marie-Andree Bolduc said Thursday that despite supply challenges, operations have normalized at the 20 stores and they now understand the needs of each outlet.
