Liberal leader Justin Trudeau and NDP leader Tom Mulcair will both be preaching to the converted at rallies in Ottawa and Vancouver respectively.

Mulcair, however, may find himself having to clarify his position on Alberta's oilsands after a comment on Friday by one of his high-profile candidates.

Author Linda McQuaig, who is running under the orange banner in the riding of Toronto Centre, said on CBC News Network's Power & Politics on Friday that much of the oil from the oilsands might have to stay in the ground if Canada is to meet its climate change targets.

The other political parties pounced on the remark, noting the contrast with Mulcair's support for a proposed east-west pipeline.

Calgary Conservative Michelle Rempel called McQuaig's remark alarming.

Conservative Leader Stephen Harper will make an announcement concerning security in Ottawa at 10 a.m. ET, and will be in Quebec City later today.

The Tories have high hopes to do well in the ridings around Quebec City in the Oct. 19 election.
