There is practically no evidence that First Council of Nicea establised the canon of the New Testament. Your source states that it promulgated early canon law, which is something else entirely. Please see my earlier post on this question.
ETA: As for the OP, assuming we discount the disputed claim for the Council of Laodicea, the earliest generally accepted example of an attempt to set forth a canon is in the 39th Paschal (or Festal) Letter of Athanasius. I know that's irrelevant to duvduv's agenda-driven question though.
