Mississauga Transit will be the first Canadian transit system to use hydrogen fuel-injection. The hydrogen unit will be placed into a bus on an experimental trial. Hy-Drive is the manufacturing company that produces the units. Hy-Drive guarantees there will be an eight per cent improvement in fuel efficiency or it will take the unit back. In some cases, reductions have reached as high as 32 per cent. With a guarantee like that this could be a way for Durham Region Transit to reduce their operating cost.
