As for Green Party Leader Elizabeth May, the only event listed on her itinerary is the debate, which suggests she may be spending the day either making or recovering from the cross-country trek from Victoria, where she launched her campaign yesterday.
"We have been telling Canadians and showing Canadians how Justin Trudeau has consistently misled them - he has lied", Scheer said.
An election campaign sure to feature plenty of pocketbook promises got underway amid deeper questions of ethics and values Wednesday as federal leaders challenged Canadians to consider the kind of country they want to vote for 40 days from now.
Conservative Leader Andrew Scheer also spoke about the SNC-Lavalin affair on the first day of electioneering.
Scheer will spend Day 1 of the campaign in Quebec and Ontario, while Trudeau will head for Vancouver, the same place he launched his bid for election in 2015.
The party, which led the pack at the start of the 2015 campaign but ended up coming in third place, is dipping in the polls and struggling to raise money this year.
Programming note: For the duration of the campaign, iPolitics AM wrangler Kady O'Malley will be writing a daily newsletter for the Toronto Star.
Scheer accused Trudeau of "fear-mongering" and reiterated his party's position that he will oppose any measure to introduce legislation on that. "You all know how proud I am to be a son and a grandson of British Columbia", he told the cheering throng, playing up his family connections to the province.
Climate change and affordability are predicted to be key campaign issues.
Under the law, the election must be October 21.
The Liberals election kick-off has been devastated by two bombshell stories by the Globe and Mail, first revealing that the Liberals are blocking the RCMP from getting the information they need for a potential obstruction investigation, and then revealing that Jody Wilson-Raybould was interviewed by the RCMP this week.
Conservative leader Andrew Scheer is thought to be Mr Trudeau's biggest rival. The People's Party of Canada has one seat and former New Democrat Erin Weir sits as a member of the Co-operative Commonwealth Federation. "Liberals believe in investing in people and in communities, which is why we are taking these steps to make homeownership an achievable dream, not just a privilege for the richest few".
"We have made the case that he has lost the moral authority to govern", the Tory leader said.
The separatist Bloc Quebecois, under new leader Yves-Francois Blanchet, will be competing for seats against the Liberals, Conservatives and the NDP in Quebec, a crucial battleground province in federal politics.
