British Columbia (Public Service Employee Relations Commission) v. BCGSEU
The Government of British Colombia established minimum physical fitness standards for fire fighters. The claimant, a woman, had previously performed her work satisfactorily but failed to meet the aerobic standard. The arbitrator found that the aerobic standard constituted adverse discrimination based on sex because men as a group have a higher aerobic capacity than women and therefore are more able to reach the standard. The Court of Appeal overturned the ruling.
