Thousands of people across Canada are celebrating the sixth annual Anti-Bullying Day by wearing pink shirts Wednesday.

In Vancouver, several events and rallies are happening across the city and hundreds of local schools have signed up to take part.

Emergency responders have also signed up. Some Vancouver police will be changing their uniforms for pink shirts, while Vancouver Fire and Rescue are adorning several trucks with large pink flags.

Anti-Bullying Day -- also known as Pink Shirt Day -- began as a protest against an incident at a Nova Scotia high school, where a boy was bullied for wearing a pink shirt.
