There were rumours at the time Hydro-Quebec intended to buy Maritime Electric as well. PEI Premier Robert Ghiz denied it and Maritime Electric said it knew nothing about a sale.
But a document released by WikiLeaks shows discussions were serious.
Most of the note, written by the American Embassy in Ottawa, refers to the proposed mega deal between Hydro-Quebec and NB Power. It outlines a discussion between Quebec Premier Jean Charest and U.S. Ambassador David Jacobson.
"Charest also told the Ambassador that Hydro-Quebec is planning to acquire the privately-owned Prince Edward Island power company," the document reads.
"The generating assets involved are quite small, but Charest said Hydro-Quebec would be also acquiring important wind assets and environmental credits."
When asked about the document, Ghiz told CBC News a deal was not imminent.
"It might have been discussed in passing, but our focus at the time was to purchase electricity from Hydro-Quebec. Now, if they had ended up purchasing New Brunswick Power, well that would have opened up the door for them to look at Maritime Electric," Ghiz said.
When the Hydro-Quebec deal with NB Power fell through it ended any potential discussions between Quebec and PEI.
