In 1991, Bob Rae appointed Brandt as chairman and CEO of the LCBO, the agency that owns and operates Ontario's publicly owned liquor stores. He was reappointed to the position four times by Rae, Harris and Ernie Eves, retaining the position for fifteen years, and remains the longest serving chair and CEO in LCBO history. He was noted for modernizing the LCBO's operations as well as convincing the provincial government not to privatize the service. He was accused of accepting inappropriate luxury trips in 1999, but was defended in the legislature and was soon after reappointed to a fourth term as chair and CEO.
