Thousands filled the Round Up Centre for their opportunity to hear the Aga Khan.

This is the first time in 16 years that his highness has been in Calgary and volunteers have been working around the clock to prepare for his visit. "We've had 3,500 plus registered volunteers and thousands more people who are just doing the work," says Naheed Nenshi the coordinator of volunteers.

The spiritual leader, of more than 15-milion Ismaili Muslims, made a stop in Calgary as part of his Golden Jubliee, which marks his 50-years as leader. "This is really the pinnacle of a faith experience for the people in this community," says Nenshi.

For this jubilee year, the Ismaili Muslims are focusing their efforts on reducing poverty. In Calgary, the Ismaili's are working with Habitat for Humanity and are helping to build a housing project in Mayland Heights.

The Aga Khan is on a week-long Canadian journey with Vancouver being his last stop.
