Letter to unitholders Unaudited Consolidated Financial Statements Supplemental
Information

GATINEAU, Québec, February 6, 2007 – Great Lakes Hydro Income Fund today reported its financial and operating results for the fourth quarter and year ended December 31, 2006.

In the fourth quarter of 2006, power generation totaled 968 gigawatthours (GWh)compared with 880 GWh a year earlier. Revenues increased to $42.0 million and income before non-cash and special items to $17.3 million. These results reflect the continued strength of the hydrological conditions in Québec and
New England.

Financial and operating results increased significantly for the full-year period. Power generation totaled 4,151 GWh compared with 3,503 GWh last year. Revenue increased by 15% to $177.1 million and income before non-cash and special items by 19% to $82.6 million. These results were driven by exceptionally strong water inflows in Québec throughout 2006 as well as improved hydrological conditions in our Ontario operations. They also include generation of 59 GWh from the Cedar Dam facility in Quebec that was commissioned in December 2005, and 34 GWh from the Carmichael Falls, Ontario facility that was acquired on July 1, 2006.

In 2006, the Fund’s cash distributions increased to $60.1 million from $58.7 million last year.

In 2006, a total of $30.2 million was invested in sustaining capital expenditures and enhancement initiatives, and $6.0 million in major maintenance. Major capital projects, many of which extend over multi-year periods, are now underway at facilities in Québec, British Columbia, Ontario, Maine and New Hampshire. It is anticipated that organic growth will add 15 GWh to the Fund’s generation in 2007 and a further 48 GWh by the end of 2009.

At December 31, 2006, the Fund had a cash balance of $31.8 million, almost $25 million of availability on its credit facilities and almost $21 million available on its hydrology reserve facilities with Brookfield Power.

“2006 was an excellent year for the Fund. Looking forward to 2007, we expect to derive the benefit of a full-year’s contribution from our Carmichael Falls acquisition as well as additional efficiency and capacity gains from our capital improvement program,” said Richard Legault, President and Chief Executive Officer.
