, Wilmot is served by a single bus route, Grand River Transit's Route 77 Wilmot. It operates on a 12-hour weekday schedule and uses "flex stops" to provide more convenient service to riders in certain areas. The route connects New Hamburg, Baden, and Petersburg to the Boardwalk bus terminal on the west end of Kitchener-Waterloo. After an initial pilot in 2016–17 which was funded by a provincial community transportation grant, the route was made a permanent part of the Grand River Transit system.
