An air quality statement for portions of southwestern Ontario has ended.
Environment Canada had issued the statement for Chatham-Kent, Windsor-Essex, and the London region, with high levels of air pollution possible throughout most of Sunday.
The weather agency had said hot and sunny conditions were expected to cause increasing ground-level ozone concentrations.
The statement was allowed to expire shortly after 9pm Sunday.
