If Michael Vick is banned for life by the NFL, would the CFL be likely to let him in?

I read in an AP article today that Vick could very well be banned for life by the NFL under the league's personal conduct policy for his involvements with dogfighting and gambling. If this were to happen, would the CFL be likely to let him join? What about "minor leagues" like the AFL? Or would it be time for Vick to hang up his cleats?
