Leaders on the move as campaign continues

Liberals and Conservatives are trading barbs this morning on the campaign trail, each targeting criticism at some of their opponents' candidates.

Conservative Leader Erin O'Toole's party started the day by questioning tax arrears that Liberal candidate Steven Guilbeault disclosed in a parliamentary ethics filing.

Guilbeault, likewise, is using a series of posts on Twitter to highlight just over a dozen Conservative candidates who deny climate change.

Canadians want real action to fight climate change – not a watered down pamphlet as proposed by the CPC.

And finally, I invite you to consult the proposals of a serious party on the indisputable question of the climate emergency https://t.co/YtfXck3Jnb #elxn44 #cdnpoli pic.twitter.com/8LOw1eNZVn

The partisan shots are starting to frame the third week of the federal campaign that wraps up with election day on Sept. 20.

They also come one day after questions were raised about long-time Conservative MP Cheryl Gallant, who in pre-election correspondence to her constituents claimed the Liberals were in favour of a "climate lockdown."

Liberal Leader Justin Trudeau, speaking in Granby, Que., says O'Toole should be careful about slinging mud at Liberal candidates because of myriad issues with some Conservative candidates.

Trudeau began his day by outlining a plan to help restore Canada's big lakes and river system. He will later head north to Nunavut with campaign stops planned in Iqaluit.

We’ve done more to fight climate change and protect our environment than any other government in Canadian history — but we can’t slow down now. Let’s keep moving forward — for a cleaner, greener future, for everyone. pic.twitter.com/32OGhWuiej

Trudeau was dogged over the weekend by obscenity-spewing protesters angry about his pandemic vaccination policies.

In Ottawa, NDP Leader Jagmeet Singh is promising to boost spending at the Canada Revenue Agency to help crackdown on "ultra-rich" tax dodgers.

He later is scheduled to fly to Ladysmith, B.C., for a meet-and-greet with supporters.

Conservative Leader Erin O'Toole, meanwhile, is sticking to the Greater Toronto Area. He begins the day at a dog sanctuary in King City, Ont., before heading to an event with supporters in nearby Markham.
