The base salary range considers many factors including but not limited to experience education and training including any collective agreement requirements for union represented positions.

For management roles the base salary range does not represent the total compensation package. The total compensation package for regular full-time management roles includes pay-for-performance programs for annual and medium time periods. Maintaining a high-performance culture and excellence is a core expectation of every member of our leadership team and is rewarded through the established compensation framework.
