There's certainly no basis for claiming that a carbon price of the magnitude talked about or being proposed and being implemented will have any likelihood of causing a recession. I think we know this intuitively. The price on carbon is equivalent to a couple of cents on gasoline and a small amount on natural gas.
These are the kinds of fluctuations we experience routinely, and they don't cause recessions. We don't have to just trust our intuition. There are reams of studies. The Canadian government has done a lot of them. Academics have done a lot of them. There's no evidence that this will have any large impact on the economy. It will be a small amount of noise. We don't really know if it's going to be slightly positive or slightly negative, but we do know that it's going to be very slight.
