A limited number of early bird tickets for Virgin Festival Calgary are available at FutureShop.com.

General ticket sales begin April 12 at Future Shop and Ticketmaster.ca.

One-day passes are $75.50 (including a $1 donation to Virgin Unite Canada), with two-day passes at $125.00 (including a $2 donation to Virgin Unite Canada). Additional info is available at VirginFestival.ca.

As noted above, part of the proceeds from ticket sales, as well as from on-site fundraising, will go to Virgin Unite Canada, the independent charitable arm of the Virgin Group which works to make an immediate, tangible difference in the lives of people in need across the world.

Festival organizers are also working to make the event carbon neutral with on-site recycling, use of biodegradable food and drink containers, use of green energy sources to power as much of the festival as possible, purchase of carbon offsets and planting trees to help ensure future carbon reduction.
