Brian Pallister's proposal to put Nellie McClung on a banknote is the focus of a New Democratic Party attack advertisement that made its debut on Thursday.
The short video calls into question Pallister's proposal, and NDP MLA Melanie Wight said the Tory leader has fought against ending women's issues by defunding public abortion clinics.
"It's so ironic," Wight said.
"It's like me choosing to put Donald Trump on a bill because [Pallister] has about as much respect for women as I have for Donald Trump."
On Thursday, Pallister said he wrote a letter to the governor of the Bank of Canada, asking for McClung to become the face of Canadian currency.
He called the leader of women's suffrage a pioneer and democratic icon.
