No. You said that in Canada you can choose between the public insurer or a private insurer. You cannot. You framed this comparison incorrectly this way in order to promote the idea of a public option which is very different. In Canada everyone gets the public single payer insurance. The parts that the public single payer insurance does not cover can be covered by buying supplemental private insurance. That is not a public option scenario.
