The Privy Council Office in a confidential August 13, 2021 memo said Liberal and New Democrat voters were more likely to get vaccinated than Conservatives. Prime Minister Justin Trudeau called a vaccine mandate election two days later.

“Partisanship was associated with intention to vaccinate,” said the memo Emerging Evidence On Covid-19. “Those who voted liberal/democrat expressed intention to vaccinate at higher rates than those who voted for other parties.”

“Those who voted Liberal or NDP in the 2019 election were most likely to indicate the intention to vaccinate compared to those who voted for other parties,” said the memo. The document was released through Access To Information.
“Alberta and Saskatchewan have the highest percentage of the population who do not intend to vaccinate,” said Emerging Evidence. The Liberal Party at the time held no seats in either province.
