          TransCanada Appeals NEB Decision to Federal Court of Appeal

CALGARY, Alberta - March 21, 2003 - (TSX: TRP) (NYSE: TRP) - TransCanada
PipeLines Limited announced today that it is applying to the Federal Court of
Appeal for leave to appeal the National Energy Board's (NEB) RH-R-1-2002
Decision issued February 20, 2003. In this Decision, the NEB dismissed
TransCanada's September 2002 request for a Review and Variance of the NEB's June
2002 RH-4-2001 Decision on the company's Fair Return application.

TransCanada is concerned with the effect of the NEB Decision on TransCanada's
ability to obtain a fair return on the company's investment in its Canadian
Mainline natural gas transmission system. TransCanada is basing its leave
application on two questions of law.

TransCanada is a leading North American energy company. We are focused on
natural gas transmission and power services with employees who are expert in
these businesses. Our network of approximately 38,000 kilometres of pipeline
transports the majority of western Canada's natural gas production to the
fastest growing markets in Canada and the United States. TransCanada has
interests in more than 4,000 megawatts of power - an equal amount of power can
meet the needs of about four million average households. Our common shares trade
under the symbol TRP on the Toronto and New York stock exchanges. Visit us on
the internet at www.transcanada.com for more information.
