        The information in this report is being furnished, not filed, pursuant to Item 2.02 of Form 8-K.

Item 7.01    Regulation FD Disclosure.

        Northern Border Pipeline Company ("Northern Border Pipeline") has advised us that the contracting status on the Port Morgan, Montana to Ventura, Iowa segment of the pipeline as of May 1, 2005 is as set out below.

Northern Border Pipeline 2005 Capacity (mmcfd)
Port of Morgan, Montana to Ventura, Iowa

 
  May
  Jun-Oct
  Nov-Dec
Maximum-Rate Firm Contracts   1,730   1,685   1,402
Discounted-Rate Firm Contracts   304 (1)  
Available Capacity   340   689   972
Total Summer Design Capacity   2,374   2,374   2,374

(1)
Average of 78% of maximum rate for one month.

        Northern Border Pipeline has advised that they have discounted rates on a short-term only basis in order to maximize overall revenues and depending on daily gas market conditions, additional daily firm or interruptible services may be sold during the month and would generate additional revenue.

Item 8.01 Other Events.

        TC PipeLines, LP owns a 30% general partner interest in Northern Border Pipeline Company. The remaining 70% is owned by Northern Border Partners, L.P., a publicly traded limited partnership controlled by ONEOK, Inc.

        Northern Border Pipeline has advised us that in April 600 million cubic feet per day (mmcfd) of firm transportation capacity on the Northern Border Pipeline was available for contracting and they believe was not sold primarily due to a high level of natural gas being delivered to Canadian storage as a result of unusually high summer to winter differentials. They have further stated that as Canadian storage continues to fill, the opportunity for contracting should improve. Northern Border Pipeline currently believes the greatest risk of unsold capacity exists during the second quarter but some weakness could continue through the balance of the year based on weather conditions and mid-continent pricing. They expect to sell substantially all of the available capacity in the November — December timeframe at or near maximum rates.

        Northern Border Pipeline had previously reported that they had a total amount of approximately 650 mmcfd of capacity available beginning in May 2005. As at May 1, 2005 Northern Border Pipeline has now advised that 340 mmcfd remains available for contracting in May. Given this confirmation, Northern Border Pipeline advises it believes that the most likely range of impact on its revenues from unsold capacity in 2005 is a reduction of $15 million to $28 million of which our share would be $5 million to $8 million.
