Vancouver is a great dance town, with three large independent studios (one is the biggest in Canada), two franchise studios and many smaller independents. There are many studios specializing in Swing or Salsa or other forms of dance, and a strong Salsa community that parties weekly at several venues. We have four major ballroom comps each year and several smaller ones, and throughout the summer DanceSport BC hosts free weekly outdoor dance parties in the heart of downtown that feature a group lesson followed by hours of social dancing. The UBC Dance Club at the University of British Columbia is one of the largest in the country. Considering that the city isn't that big in comparison to other North American cities, dance is proportionately huge here. Other Canadian cities that are known for dance are Montreal and Calgary.
Every night of the week you can enjoy a social ballroom dance on a full-sized floor at one of the large studios here, plus three tea dances weekly during the day.
In contrast, when I travel to Orange County with more than 10 times the population, I'm hard pressed to find any venue with a full-sized floor that offers social dancing more than one night a week. Even Seattle, with three times the population of Vancouver, has nothing similar to offer.
