NEWS RELEASE

Enbridge to Monetize Investment in AltaGas Income Trust

CALGARY, Alberta, July 20, 2004 — Enbridge Inc. (“Enbridge”) and AltaGas Income Trust (“AltaGas”) announced today that AltaGas has filed a preliminary prospectus with the securities regulatory authorities throughout Canada in connection with a secondary offering of Trust Units of AltaGas by Enbridge. The offering is being underwritten by a syndicate led by Scotia Capital Inc., CIBC World Markets Inc. and RBC Capital Markets. The offering will be approximately $225 million and is expected to close on or about August 10, 2004. AltaGas will not receive any of the proceeds from the offering.

“The AltaGas investment has been a good investment for Enbridge,” said Patrick D. Daniel, President & Chief Executive Officer of Enbridge. “However, the timing is right to sell part of our AltaGas investment and prudently reinvest the gain, together with our original capital, in other North American energy infrastructure that is more closely aligned with our core businesses.”

David Cornhill, Chairman and Chief Executive Officer of AltaGas said “Since Enbridge made its initial investment in AltaGas five years ago we have tripled our asset base and grown our market capitalization by six times to over one billion dollars. Enbridge has been a good financial investor and received very good returns on their investment. We are supportive of their disposition and are pleased with the opportunity to realize our full growth potential and deliver substantial unitholder value to an expanded unitholder base.”

Enbridge Inc. is a leader in energy delivery in North America. Enbridge owns and operates, in Canada and the U.S., the world’s longest crude oil and liquids pipeline system, and Canada’s largest natural gas distribution company, providing gas to 1.7 million customers in Ontario, Quebec, New Brunswick and New York State. The Company also is involved in international energy projects, and the natural gas transmission and midstream businesses. The Company employs approximately 4,000 people, primarily in Canada, the U.S. and South America. Enbridge common shares trade on the Toronto Stock Exchange in Canada and on the New York Stock Exchange in the U.S. under the symbol “ENB”.

AltaGas moves energy from its source to the end user, adding value through the process. Its steadily expanding asset base today includes natural gas gathering and processing facilities, interests in ethane and natural gas liquids extraction plants, and transmission pipelines. AltaGas distributes natural gas to Alberta customers through AltaGas Utilities Inc., to customers in the Northwest Territories through the Ikhil Gas Project and distributes gas in Nova Scotia through its interest in Heritage Gas Limited. The Trust provides energy services to customers, including marketing of natural gas and natural gas liquids and sale of power from its power purchase based arrangements. AltaGas’ Trust Units are listed on the Toronto Stock Exchange under the symbol ALA.UN.

This news release does not constitute an offer to sell or a solicitation of an offer to buy the Trust Units in any jurisdiction. The Trust Units offered have not been, and will not be, registered under the United States Securities Act of 1933, as amended, and may not be offered or sold within the United States of America.

Enbridge realizes gain on sale of AltaGas Trust Units

CALGARY, Alberta, July 21, 2004 — Further to its announcement of July 20 identifying its intent to divest a portion of its investment in AltaGas Income Trust (“AltaGas”), Enbridge Inc. today announced that it has sold 11,650,000 Trust Units of AltaGas representing approximately 64% of Enbridge’s total investment in AltaGas. The Trust Units were sold to a group of Canadian underwriters at a price of $19.75 per unit.

In addition, the underwriters have been granted an over-allotment option to purchase an additional 1,747,500 Trust Units at the issue price of $19.75 per unit at any time up to 30 days after closing of the offering. The sale, excluding the over-allotment, will realize net proceeds to Enbridge of approximately $217 million and will close on or about August 10.

Excluding the over-allotment, net proceeds from the sale of Trusts Units will generate a resulting pre-tax gain of approximately $72 million, which will be recorded in the Company’s third quarter results, and the Company’s remaining interest in AltaGas has decreased from approximately 36% to 13%.

Patrick D. Daniel, President & Chief Executive Officer of Enbridge, said, “The AltaGas investment has been and continues to be a good investment for Enbridge. However, we decided the timing was right to sell part of our AltaGas investment and reinvest the proceeds in other North American energy infrastructure that is more closely aligned with our core businesses — liquids pipelines, gas pipelines and gas distribution. We will continue to monitor our remaining investment in AltaGas.”

The underwriting syndicate was led by Scotia Capital Inc., CIBC World Markets Inc. and RBC Capital Markets, and included BMO Nesbitt Burns Inc., National Bank Financial Inc., TD Securities Inc., Clarus Securities Inc., HSBC Securities (Canada) Inc., Canaccord Capital Corporation, FirstEnergy Capital Corp., HSBC Securities (Canada) Inc. and Peters & Co.
