Police in White Rock say the city's main town has broken apart and one person is caught as strong winds and high waves batter and dock,
Cst. Chantelle Sears said the police had been told about the situation about 2 p.m. Thursday.
"Because of the winds, the pier has broken separately," said Sears. "There is one person who needs to be saved from it."
The pier is on Boundary Bay in the 1500 block of Marine Drive.
Victoria Co-ordination Center, an agency of Canadian Forces co-ordinating air and sea rescue at B.C. and Yukon, confirmed that he had sent an helicopter ambulance to rescue the person.
Social media videos of the scene show the drainage cracking violently in the waves.
