The Halifax Regional Municipality says Oakfield Park Beach in Oakfield was closed on July 16 so toxin levels could be tested after what appeared to be blue-green algae was spotted in the water. HRM says the beach has reopened as toxin levels are within Health Canada limits according to test results, and no new algae has been seen.
