The event has added Calgary to its list of 10 Canadian cities on its upcoming North American tour.
Dates for the two Calgary shows haven’t been released yet, but Edmonton takes place July 23.
Last year, thousands of people slid down in 10th Street in Kensington on inflatable tubes. The vinyl waterslide is the length of three football fields.
The event had its share of problems, including the fact the slide was late arriving in the city.
Other cities include North Vancouver, Penticton, Saskatoon, Winnipeg, Toronto, Montreal, Quebec City and St. John’s.
