A senior Bombardier official responded to Toronto Mayor John Tory’s Thursday letter hinting at further legal action against the company regarding streetcar delivery delays, saying they have already doubled their output.

Tory’s letter said the city was considering further legal action over and above an existing $50 million claim for late delivery of streetcars, after TTC staff said they were “not confident” Bombardier would be able to deliver all 204 vehicles by the end of 2019.

In May, Bombardier released an updated schedule, promising to provide 16 new streetcars by the end of 2016 and 40 new streetcars in 2017.

In 2018, Bombardier says it will provide 76 new streetcars to the TTC and 58 in 2019. TTC staff says that works out to a rate of approximately one car every 3.3 days in 2018 and one every 4.4 days in 2019.

In his response, Bombardier Transportation Americas President Benoît Brossoit says the company has “doubled out production output over the last three months.”

“Based on these results we are fully confident that we will meet our commitment to deliver an additional 40 new streetcars in 2017 and all 204 by the end of 2019.”

He said that understand the company “may have failed to meet your expectations” but added that the slow delivery of streetcars “does not reflect the type of company Bombardier is around the world.”

A total of 30 streetcars will be in the TTC’s possession by the end of the year, the company says.
