The Conservatives' lead over the Liberals has grown again, according to the latest Nanos Research daily tracking poll.

Conducted exclusively for CP24, CTV and the Globe and Mail, the poll finds the Tories with an 11-point lead over the second-place Grits.

The Conservatives have the support of 41 per cent of decided voters, while the Liberals have 30 per cent. In third, the NDP have 15 per cent, followed by the Bloc Quebecois with seven per cent and the Green Party with four per cent.

Eighteen per cent of the 982 Canadians who were polled between Friday and Sunday were still undecided.

The poll is considered accurate to within 3.1 per cent, 19 times out of 20.

Meanwhile, the party leaders who are invited to this week's televised debates are scaling back their appearance as they prepare for the key events.
