Fluoride will be reintroduced to Windsor's drinking water by the fall.
The Windsor Utilities Commission had set a timeline for later this year, but hadn't released a firm date.
An update was provided to the Windsor-Essex County Health Unit Thursday.
Officials tell the health unit that the process will be complete by November.
They say the COVID-19 pandemic and work to fine-tune procedures had delayed the launch.
Reintroduction will cost the city $850,000 and then $150,000 a year for system maintenance.
Fluoride was removed from city water in 2013.
