Thousands became sick and others died.
Despite being 14 years ago this month, the Walkerton water contamination tragedy is still fresh in the minds of Ontarians.
Premier Kathleen Wynne stresses she isn't using the tragedy for political gain as she made a campaign stop there Thursday . She spoke of what the loss of 100,000 public sector jobs promised by the Tories might do and is being criticized for it.
Wynne says the province needs to learn from the past, pointing to Mike Harris-era cuts in the 90's leading up to the tragedy.
The premier committed to $30 million in funding over 10 years for the Walkerton Water Treatment Centre if re-elected.
Progressive Conservative leader Tim Hudak says it's sad that the premier of Ontario is trying to take advantage of what happened in May of 2000.
Hudak says that's something he expected of her predecessor, Dalton McGuinty.
NDP leader Andrea Horwath says it's up to the premier to decide how to run her campaign.
