Acting on the request of STM transit authority, Quebec Toponomy Commission officially changed the names of twenty of the Montreal Metro stations. The move is aimed at standardizing the names of the stations with toponymy guidelines of the city. The article “du” has been appended before the names of all stations, the only exception being Square-Victoria which has been renamed to du Square-Victoria-OACI to represent the headquarters of UN Civil Aviation Organization.
The move is likely to cost over $125,000 for updating the signage and the recordings that run in the trains and stations.
