What are the employer's obligations to ensure a discrimination-free workplace?

In 1999, the Supreme Court of Canada case Meiorin adopted a new standard unified approach to ensure a discrimination-free workplace.  

The court clearly imposes a duty on the employer to make every reasonable effort, short of undue hardship, to accommodate workers and to proactively eliminate any employment policy or practices that may discriminate against individuals or groups of individuals based on the grounds enumerated in the CHRA.

Since Meiorin, there is now a positive obligation on employers to design workplace standards that will enshrine the spirit of equality and a discrimination-free workplace through its practices and policies.
