The Liberal leader, speaking to supporters at a cafe in the NDP-held riding of Beaches-East York, touted progressive policies he has promised if elected on Monday while likening NDP Leader Tom Mulcair's platform to that of Harper.
Trudeau's pitch included a nod to a local family who, he said, are working to pay down debt while saving for their children's education. Trudeau said his plan, which includes a tax cut for the middle class, would put $5,100 back into the family's pocket.
His remarks were an apparent response to the Conservatives' event on Monday, during which Harper, with help from a working mom, added up the purported impact the Liberal and NDP plans would have on the finances of everyday Canadians.
With some polls pointing toward a Liberal minority government, Trudeau is under pressure to win over NDP faithful and, to that point, continued to rebuff talk of potential co-operation with Mulcair during a question and answer session with reporters.
All three major party leaders will make stops in Toronto and elsewhere in vote-rich Ontario today.
