Bombardier is laying off half of the workforce at its Thunder Bay plant.Two major Ontario contracts for TTC streetcars and Metrolinx GO Transit rail cars are slated to halt by the end of the year. Local union spokesman Dominic Pasqualino fears more job losses are on the way beyond these 550 jobs as the contracts wind down. He says part of the blame for a lack of new contracts lies with the Trump administration, which has backed Buy America-like clauses requiring a minimum threshold of local content. Last month, Conservative MPP Greg Rickford said Metrolinx extended an offer for 36 additional rail cars to Bombardier, but Pasqualino says the plant needs 10 times that amount to sustain employment.
