Tornado alerts sent as soon as warning issued: Environment Canada

TORONTO – Environment Canada says it sends alerts to cellphones as soon as a tornado warning is issued, but the fast pace and unpredictable nature of twisters mean some residents may not receive the emergency message before one hits.
The weather office has faced criticism for the timing of its alert regarding Thursday’s tornado in Barrie, Ont., which ravaged a neighbourhood in the city’s south end and sent multiple people to hospital.
Some have reported receiving the alert only moments before it touched down — or even after.
