Saanich School District Supt. Keven Elder would not provide details on the video, but says Joe Winkler sent parents an email acknowledging he inadvertently showed his elementary class an inappropriate clip.
Winkler's email, obtained by CTV News, told parents that an unclothed woman was seen posing provocatively on the sand, though no explicit nudity was shown.
Winkler said he was shocked while showing his class a music video that the nude woman was shown.
The teacher at Keating Elementary School in Central Saanich has been suspended in the past for a similar incident at different school.
In 2012, Winkler showed students a video of cross-dressing men on a beach lip-syncing a Christmas song. (CFAX, CTV)
