Our Pipelines

Trans-Northern Pipelines Inc. (TNPI) operates two pipeline systems in Canada. Both are underground and transport refined petroleum products such as gasoline, diesel fuel, aviation fuel and heating fuel.

Ontario-Quebec Pipeline

We operate 850 kilometres of pipeline in Ontario-Quebec. The pipeline flows east to west, linking Montreal, Quebec and Oakville, Ontario and west to east between Nanticoke and Toronto, Ontario. There are also branch lines which connect Toronto’s Pearson International Airport, Montreal’s Pierre Elliot Trudeau International Airport, as well as Clarkson and Ottawa, Ontario.

This pipeline safely transports an average of 27,500m3 or approximately 172,900 barrels of refined fuel products daily.

The pipeline is regulated by the National Energy Board (NEB), the agency responsible for regulating pipeline activities in the interests of the Canadian public.
