NDP MP Don Davies, the party's health critic, said Poilievre has peddled "misinformation" about this legislation.
The bill would only ban COVID-19 mandates — but some Conservative Party literature has suggested it would prevent future vaccine mandates.
While agreeing with the Conservatives' claim that Trudeau and the Liberals "politicized" Canada's pandemic response, Davies said passing this legislation could tie the hands of the government if COVID-19 returns as a pressing public health threat.
Davies said the decision to impose a vaccine requirement should "always be based on the best available evidence, current science and advice of experts," not Conservative MPs "with little or no background in any of those things."
