On August 7, 1979, the Woodstock area was hit by three tornadoes, two of which registered at least F4 on the Fujita Scale. On the west side of town along Ingersoll Road, a Dominion Food Store was heavily damaged while the tornadoes skipped over every other home and business. Dickson's Florist was wiped out and the Fry home was moved on its foundation. Father Grondziel of the new Polish Roman Catholic Church, next to the Dominion Food Store, had just stepped into the washroom when one of the tornadoes passed by and took off the roof of the church and everything in the room he had just been in. No one on the street was injured and the cleanup took many weeks. On the south side, the buildings of the Maranatha Christian Reformed Church and the John Knox Christian School were destroyed, and the only fatality occurred when a vehicle on Highway 401 was blown off the road and the lone occupant killed.
