153. The Société de transport de Montréal may order expropriation outside its territory where it considers expropriation necessary for the purposes of the subway tunnel, lines, subway car garages, workshops, platforms, structures thereon and rectifier or ventilation stations.
The Société must, however, propose to the city concerned that it proceed with the expropriation, at its own expense, unless the city has already indicated its intention not to expropriate or the right is of the nature of a servitude or affects only the subsoil. The city has 90 days to accept, by resolution, the proposal of the Société failing which the city is deemed to have refused. The city may, however, within those 90 days, transfer its right to expropriate to the public transit authority in its territory.
The city or, where applicable, the public transit authority concerned, is the owner of the expropriated property, subject to its obligation to transfer to the Société de transport de Montréal, free of charge, the property necessary to its work.
Where expropriation is made by the Société de transport de Montréal, the Société shall transfer to the public transit authority concerned, free of charge, all property that is not necessary to its work.
