HAMILTON, Ontario, Sept 23 (Reuters) - Canadian Prime Minister Justin Trudeau pledged on Monday to create a national prescription drug plan if re-elected, moving back on the offensive after blackface photos of him emerged last week and hurt his campaign.
After two days of profuse apologies, Trudeau has resumed making campaign announcements as polls show his Liberals trailing the opposition Conservatives of Andrew Scheer slightly ahead of the Oct. 21 election.
Trudeau, accusing the Conservatives of planning major spending cuts, said he would make sure all Canadians had access to a family doctor and affordable medicine.
"No one should go without the care they need because they don't have access to a family doctor. And no one should have to give up food and heat to be able to pay for healthcare," Trudeau told reporters in the southwestern Ontario city of Hamilton.
Canada's universal healthcare system does not include universal coverage for prescription drugs, and primary care doctors are scarce in many areas.
The cost of the proposal would be about C$6 billion ($4.52 billion) over four years, and Ottawa would work with the 10 provinces and three northern territories to implement the changes, Trudeau said.
The healthcare pledge was his fourth major campaign announcement since last Friday, when he vowed to ban military-style assault weapons. On Sunday he pledged to eliminate some taxes and slash cellphone bills by a quarter.
The ruling Liberals were knocked off course by old photos of Trudeau in blackface that emerged last week. The images were at odds with his oft-stated position that he wants to improve the lot of minorities in Canada and prompted international ridicule.
Foreign Minister Chrystia Freeland, the most visible member in Trudeau's Cabinet, told Reuters on Friday that the prime minister had her full confidence. Other Cabinet members, legislators and candidates have also made it clear the Liberal Party is standing squarely behind its leader.
But Trudeau still faced more questions about the photos on Monday, five days after Time magazine released the first picture.
"I am continuing to be open with Canadians about the mistake I made ... I should have known better but didn't," he said.
Tejinder Singh, who is of Indian descent, said the pictures will not change his vote. "He has been very good to us. I am not interested in the photos. We support him," Singh said in the town of Stoney Creek, east of Hamilton, earlier on Monday.
