Prince William and Kate Middleton began day four of their eight-day royal Canadian tour by paying a visit to the University of British Columbia Okanagan, where they interacted with student leaders and took keen interest in their research work.

"They seem to really be focusing on groups that normally don't get to be in the presence of distinguished visitors which I think is great. They're reinventing the image of royalty and what the royal family stands for," Professor Deborah Buszard, Vice-Chancellor and Principal of UBC Okanagan, told People Magazine.

Later, they sat for a Volleyball game by the university's nationally-ranked women's team, followed by a visit to the Taste of British Columbia Festival at the Mission Hill Family Estate, Kelowna. At the food fest, the royal couple sampled some of the food items prepared by local chefs and toured the vineyard; Prince William even cut out a bunch of grapes from the yard. They wrapped up the day with a brief interaction with Canadian Rangers at the airport in Whitehorse, Yukon.
