TransCanada has filed Eastern Mainline project description for the Eastern Mainline project with the National Energy Board of Canada.

As part of the proposed project, the company will add new facilities to its existing Canadian Mainline natural gas transmission system in southeastern Ontario.

TransCanada president and chief executive officerRuss Girling said that the new pipeline infrastructure will be Canadian Mainline system’s vital addition to meet the needs of Ontario and Quebec gas consumers.

"We are committed to ensuring that gas transmission capacity is available to meet the needs of customers and that the cost of serving those customers does not increase as a result of the transfer of a portion of the Canadian Mainline to Energy East,"Girling added.

The proposed project ensures that appropriate levels of capacity are available to meet the needs of existing shippers as well as the new firm service commitments contracted by TransCanada for services in the Eastern Triangle segment of the Canadian Mainline.

As much as 370km of up to 36inch diameter pipe and associated compression facilities adjacent to existing Mainline facilities between the City of Markham and the Township of South Dundas in Eastern Ontario will be constructed as part of the project.

"We remain focused on continuing to gather the public’s input to ensure we address local issues in our planning and design not only for Energy East, but also for the Eastern Mainline Project. Outreach for the Eastern Mainline Project will begin in the coming weeks."
