Well if the battery went to VMC, Then what about MTB?

Canadian transit authorities considering the repowering process are also likely to find attractive the fact that MTB’s entire product, from propulsion chain to battery, is Canadian-made. MTB, which has been in the bus repair and refurbishment business for 35 years, purchases its batteries from a Mississauga company, and the motors and engineering work are sourced from Quebec.
