MONTREAL (AP) _ A week before Quebec's 5 million voters decide whether they want independence from Canada, a poll published Saturday found the race too close to call.

According to the new poll, 45.8 percent of people said they would vote ``yes'' for independence on Oct. 30, while 42.2 percent said they would vote ``no.'' The separatists need 50 percent of the vote to win.

The survey of 1,005 voters between Monday and Friday was conducted by Leger and Leger for the Toronto Globe and Mail and Le Journal de Montreal. It had a margin of error of 3.1 percentage points.

It was the third poll in a week to show the ``yes'' side with a slight edge _ and the third to show that neither side had 50 percent of the vote.

Daniel Johnson, leader of the anti-separatist Quebec Liberals, appealed to Prime Minister Jean Chretien on Saturday to help his cause by offering to make constitutional changes that would recognize Quebec as a separate society.

``It would be desirable from our perspective that an increasing number of political leaders in Canada, as some already have, echo our view of what the future holds for Quebec as part of Canada,'' he said.

But the prime minister refused.

``We're not talking about the Constitution,'' he said. ``We're talking about the separation of Quebec from the rest of Canada.''

Lucien Bouchard, head of the separatist Bloc Quebecois in the federal parliament, was encouraged by the latest poll results, which gave his side a slightly larger edge than previous polls.

``In fact, a Yes victory is at our doorstep,'' he told a rally in Baie-Comeau.
