More than 1,000 people in Vancouver have taken off their clothes to take part in a charity run this weekend.
Runners wore their underwear
to raise awareness and money for cancers that occur below the waist, as part of the sixth annual Underwear Affair.
Participants took part in either a ten-kilometre run or five-kilometre walk through Vancouver's False Creek and raised $630,000 (£394,000) for cancer research.
According to the British Colombia (BC) Cancer Agency, almost half of all newly diagnosed cancers in the state are so-called "underwear cancers," such as ovarian, testicular, cervical and bladder cancer.
The Underwear Affair organisation raises money for the BC Cancer Foundation through a series of fun runs across different cities in Canada, as they attempt to remove the taboo associated with the disease.
