NDP MP Charlie Angus has introduced a private member’s bill calling for a ban on what his party calls 'misleading, deceptive' fossil fuel ads. The NDP says the bill would take the same approach Ottawa took to tobacco ads in 1990s. While there is predictable opposition to the bill from the oil and gas industry, others see the bill as a very modest step towards what is needed.For an assessment of the bill, we speak with Peter Dietsch, a professor in the Department of Philosophy at the University of Victoria.
