A building on airport property and a nearby plant nursery were also damaged.
The NWS said it received reports of damage east of the airport, "indicating the tornado may have continue to skip east, south of Canby."
Video from KGW viewer Linda Guttormsen appears to show the tornado from a distance.
The tornado, which was reported at around 3:45 p.m, prompted the NWS to issue a Tornado Warning in parts of nearby Clackamas County, including Canby and Barlow, until 4:15 p.m. The warning expired at that time, as the storm had weakened passed, according to the NWS.
Canby resident Linda Tate said she was shaken up when she went outside and saw the tornado.
"When I came out, I looked around and didn't see any clouds until I turned around due north and there it was, and there was no mistaking that it was [a tornado]. It was dark enough that I knew," she said.
A Tornado Warning means a tornado has been reported and conditions are favorable for more tornadoes to touch down.
