Organizers say it's going to be the biggest Pink Shirt Day ever this year.
The event, now in its sixth year, aims to take a stand against bulling throughout Vancouver and around the world.
Dave Teixeira says students at hundreds of schools will wear their pink shirts and buttons today, joined by police, paramedics, firefighters, bus drivers and others.
"So far, we've sold over 70,000 T-shirts, and what's great about this of course is that all the proceeds go to the CKNW Orphans Fund and also to the Boys and Girls Clubs to combat bullying."
BC Place even turns pink today.
Organizers hope to raise $200,000.
