Canada's first-ever national HIV prevention campaign was led by AIDS Vancouver and a national advisory team of partner HIV/AIDS organizations across the country in Edmonton, Winnipeg, Toronto, Montreal, Halifax, and a national organization in Ottawa to develop and implement the campaign in each of the six main centers this year. The National Advisory Team partners are listed below.

The campaign, which brought the images to trash boxes and billboards across Canada, specifically targetted gay men. The ads, based on an edgy US campaign prompted men to ask themselves what they might know about a sex partner. Archived materials about the campaign are available at www.think-again.ca.
