A severe thunderstorm in LaSalle, Greater Montreal, caused a bounce house to be lifted into the air, resulting in a three-year-old being critically injured after it crashed back down. The incident occurred around 4:25 PM at Ouellette Park during a family gathering. Paramedics assessed 11 individuals at the scene, with six, including four adults and two children, transported to the hospital. Witness Rosella Peluzzo described the chaotic scene as strong winds swept through, lifting the inflatable structure approximately 12 feet high. LaSalle Mayor Nancy Blanchet expressed her sadness over the incident and emphasized the community's commitment to public safety. The Environment and Climate Change Canada had previously issued a severe thunderstorm warning for the region, cautioning residents about potential hazards from strong winds and hail.
