VBA257 is an experimental television station in Toronto, Ontario's Etobicoke district, owned and operated by Humber College via its Broadcast-Broadband Convergence (B²C) Lab.^[1] The station has three transmitters in a DTS configuration covering much of Etobicoke from the University of Guelph-Humber in the central part of the city, Humber College's campus in New Toronto along the shore of Lake Ontario, and the Humber Centre for Trades & Technology in the north end of the city.

VBA257 is Canada's first ATSC 3.0 station, serving as an experimental test facility. The station broadcasts on two channels, UHF 22 and UHF 28, both of which are in a DTS single-frequency network. Each airs three subchannels: two of which are 16:9 720p video loops of landscapes, while the third is a DTV radio audio-only feed in Dolby AC-4. The station broadcasts using a particularly robust modulation configuration, to allow for reception of a weaker signal in more distant areas than its tower height and power would suggest, though at the expense of a lower total bitrate for the channel.
