An OPP helicopter rescued an adult and two children from the Minnesing Wetlands in Springwater, Ont., on Sunday.
Officers say they received a report just after 6 p.m. of three adults and two children who went canoeing and were in need of help.
According to police, the paddlers ran out of water and had minimal cellphone power.
With the help of an OPP helicopter, a father and his two children were plucked from the wetlands. The two other men declined assistance and advised that they are experienced outdoorsmen.
All the people involved are now safe and without injury, police say.
