Wynndel Post Office was opened 1 September 1910, located within the CPR right-of-way across the road from Duck Creek Railway Station (see sketch by Postmaster). [Without specific evidence, it is presumed that residents first requested that their Post Office be named to match the railway station, in turn named in association with the adjacent watercourse; such request would have been turned down by the Post Office Department in Ottawa, due to duplication elsewhere in Canada.]

After Wynndel, one of the oldest and most successful fruit ranchers of the neighbourhood. Note that local residents discount this origin. One local theory holds that a NWMP officer named Wynn was with Samuel Steele at Wildhorse Creek c1885, and later served with distinction in the Boer War, 1900.
