Singh said he is open to having a private conversation with the Liberal leader, declining to disclose what he'd say.
"Canada's firearms community is the go-to "whipping boy" of the Liberal party - guaranteed to deflect attention away from the latest Liberal scandal of Justin Trudeau's racist past", he said.
That party was shopping its policy on expanding public coverage for drugs and dental care on the campaign trail Friday, while Conservative Leader Andrew Scheer was also campaigning on the health-care theme, pledging $1.5 billion to buy new medical imaging equipment for facilities across the country.
Wynne said she is anxious about Canada's global reputation, given that people in other countries don't follow Canadian politics closely and therefore don't know about his policies. "I'll make it easy, is it possible for you to round to the nearest five?" one audience member asked during the campaign stop, prompting some cheers from the crowd.
Wynne, who supported and actively campaigned for Trudeau in 2015 when she was the Liberal premier, said in an interview that she was upset and angry to see the images, because Trudeau should have known better, especially by age 30.
Liberal Leader Justin Trudeau is promising to ban all military-style assault rifles as part of a broader gun-control plan that would also take steps towards giving cities more powers to restrict and ban handguns.
"Of course I am disappointed in his behaviour in 2001", said Audrey Festeryga, Liberal candidate for Essex. He said he had made a number of calls to "friends and colleagues" and will have many more to make. He says he never talked about it publicly because he's embarrassed. That revelation prompted the Liberal Party to go temporarily suspend its campaign until that afternoon when Trudeau again appeared before journalists, this time in Winnipeg for another apology. "There's a contrast between the rhetoric and the reality, and in a situation like this there is a perception that he would have treated people differently from the way he wants to be treated".
"What we've seen from this prime minister is there's apologies, but they don't come with any kind of remedy", he said.
Meanwhile, 29.3 per cent of respondents said Scheer would be their preferred pick, down one per cent.
"Seeing the prime minister in brownface/blackface is deeply saddening", executive director Mustafa Farooq said in a statement, before Trudeau spoke Wednesday.
Trudeau doesn't have any more official campaign events today.
Trudeau received plenty of positive comments and unrelated questions at the event, and there were just two questions about the blackface and brownface controversy. "But to win the election with a majority he's going to need to make some gains and that's going to perhaps going to be harder after this scandal and the ones that came before it".
"It was a costume party, Arabian nights, Aladdin", said Khurana, a Sikh Indian who had two children at the school at the time.
On Wednesday news broke that Trudeau had donned brownface at a social gathering at the Vancouver private school he taught at back in 2001. The picture shows him sitting with a dark-skinned man and smiling.
But he said he was only interested if the discussion were honest and not part of "a Liberal PR campaign" to help Mr Trudeau overcome the political crisis.
Lydia Miljan, a political science professor at the University of Windsor, called the images of Trudeau with dark makeup "pretty shocking", but said he did everything he could do from a "crisis communications standpoint".
