A new transformer to replace the broken one that caused a blackout in parts of Montreal over the weekend arrived at the Hampstead substation on Wednesday. The substation serves residents of Côte Saint-Luc, Notre-Dame-de-Grâce and Hampstead. The broken transformer meant the Hamstead substation, which is actually located in Côte Saint-Luc, was operating at 75 per cent. The new transformer arrives at the Hamstead substation in Côte Saint-Luc on Jan. 29, 2026. The Crown utility explained that was done to strengthen the grid while the broken transformer was replaced.
