The Fund has determined that of the monthly distributions paid to Canadian unitholders in 2006, 31.43 percent should be reported as a non-taxable return of capital, 23.89 percent as an eligible dividend and 44.68 percent should be reported as the taxable portion.

Canadian unitholders holding their Great Lakes Hydro Income Fund in a Registered Retirement Savings Plan, Registered Retirement Income Fund or Deferred Profit Savings Plan should not report any income related to distributions on their 2006 income tax return. Unitholders holding their units outside such plans will receive a T3 Supplementary Information slip from their broker or intermediary, postmarked on or before March 31, 2007.

2006 U.S. Unitholder Tax Information

The Fund believes that for U.S. federal income tax purposes the units of the Fund will more likely than not be properly classified as equity in a corporation, rather than as debt, and that dividends paid to its individual U.S. unitholders should therefore be treated as qualified dividends. As such, the distributions made during 2006, considered dividends, should qualify for the reduced rate of tax applicable to certain capital gains.

With respect to cash distributions paid in 2006 to U.S. individual unitholders, 27.27 percent should be reported as a non-taxable return of capital and 72.73 percent should be reported as qualified dividends.

The Fund is not required to issue Form 1099-DIV’s; however, U.S. unitholders may have already received this Form from a broker or intermediary that may not be correct. Consequently, U.S. unitholders should consult their brokers and tax advisors to ensure that this information is correctly reflected on their tax returns. Brokers and intermediaries may or may not be required to issue amended Form 1099-DIV’s.
