Car Free Day Vancouver is an annual event based on the community traditions of four neighbourhoods. Hundreds of thousands come out to the streets to have a day-long festival and promote active transport, public spaces and reduce carbon emissions. This a great day for pedestrians, cyclists, and rollerbladers. The usually busy streets turn into a place for huge parties, live entertainment, market stalls, food vendors, music, and fun.

Every June the West End, Commercial Drive, and Main Street communities celebrate Car Free Day, while their colleagues from the Commercial Drive celebrate in July and the North Shore fellows—in August. Around 25,000 people took part in the first Vancouver Car Free Day in 2005, and since then the number of attendants has only been growing. These street parties have become so popular, that in recent years people celebrated not one but two days. The main goal of such events is to remind people of their impact on the city's ecology and to decrease the dependence on cars and encourage more active alternative forms of transportation.
