The executive, who took up the role in September last year, is leaving to work in the private sector.
Moore became interim president and CEO due to the absence of Jim Lightbody, who is currently undergoing cancer treatment and recovery.
According to the BCLC Board, a new interim president and CEO will be chosen to replace Moore while Lightbody continues to recover.
Commenting on Moore’s resignation, Peter Kappel, BCLC board chair, said: “On behalf of the Board of Directors, I would like to thank Greg for the incredible contribution he has made to help redefine BCLC’s approach to business and corporate culture.”
Last financial year, BCLC generated revenue of C$2.53bn (US$1.95bn) for the full year, down 2% year-on-year. That was below the company’s projection of $2.64bn for the 12 months.
Of the operator’s segments, casino and community gaming was the primary source of income, with revenue totalling $1.83bn, down 4% from 2018/19.
The operator attributed the decline in revenue primarily to the impact of the COVID-19 pandemic, which forced BCLC to close all gaming facilities in March.
