Windsor police says it happened Tuesday afternoon around 5 p.m., as a severe thunderstorm pushed through the region.
Police say the man was found lying face down on the sidewalk in the 400 block of Victoria Avenue. Investigators believe he was walking along the sidewalk when the tree fell.
He’s since been transported to hospital in critical condition.
The same system has brought down large branches across the city and has downed hydro wires.
