Search efforts continue for a missing swimmer near Pinery Provincial Park.
Lambton OPP were called at around 1 p.m. on Wednesday, August 26 for a report of a missing 28-year-old from Scarborough, who was last seen at the park's beach.
Police said two OPP vessels continue the search, along with the OPP Underwater Search and Recovery Unit and OPP Aviation Services.
The Joint Rescue Coordination Centre (JRCC) and Anishinabek Police Service are also assisting in the search.
The response comes just months after a similar tragedy at the park over the Victoria Day long weekend, when emergency crews responded to five people in distress on a raft in Lake Huron.
One person, a 22-year-old from Nepal, went missing during that incident, and their body was recovered on May 29.
