"June 24, 1997. Lantz, Nova Scotia, Canada, F0 tornado touches down in local ball field at approx. 4:45pm ADT. Golf ball sized hail and intense lightning also reported with this storm"
"Pugwash, Nova Scotia, August 18 (1999). A small tornado strikes causing some localized structural damage. There were no serious injuries."
I can't speak for the Lantz tornado but the one in Pugwash definitely occurred. It was summer and at the time my aunt was working the Caboose Restaurant which was hit by the tornado. There were no injuries but the building was damaged and as a result the restaurant never reopened.
I've never seen a tornado but I have seen waterspouts on the Northumberland and though I can't confirm it I think my family's cottage was hit by one (just a wall of water coming out of nowhere with some power behind it).
