Isabelle Webster, 3, and her family were away from their home when the storm struck Monday, CBC News said.
Heavy rain, hail and several tornadoes hit the city.
When they returned to their Regina home, they found that Isabelle's playhouse had been picked up and smashed into the ground, CBC News said.
A photo of Isabelle looking upset became popular on social media sites, and retailer Canadian Tire told the family Thursday that it will donate a brand new playhouse to Isabelle.
