The tornado, which received a rating of F3 on the Fujita Scale, extensively damaged Sudbury and inflicted an estimated CA$17 million (1970 CAD) to the area.

[4] The first public indication of the twister, instead, was a phone call to CKSO from a woman frantically reporting that her house was blowing away.

[14] Minor damage was also reported to the Big Nickel, with some pitting of the stainless steel panels as rocks and debris hit the monument, although that structure also survived.

[15] Damage was also reported to Memorial Hospital, Glad Tidings Tabernacle, and over 300 homes in Lively, Sudbury and Field.

[16] In Field, a lumber mill which was the town's primary employer was heavily damaged,[17] and a church roof was ripped off just minutes after parishioners had left the building after the end of the morning mass.
