  • In May, the water supply of Walkerton is contaminated by E. coli bacteria, which leaves seven dead and thousands made ill. The toll includes OPSEU member Betty Trushinski, a dietary services worker at the South Grey Bruce Health Centre. The tragedy highlights cuts to public services. The Ministry of the Environment had cut more than 900 staff, and eliminated 80 per cent of water sampling stations. OPSEU insists on (and gets) whistle-blowing protection for members who testify at the inquiry into how it happened.
