[6] When he was eight, he told his parents that he wanted to switch to goaltender because, he said, "I liked the big goalie pads, and I thought having a catching glove was cool.

[7] After playing for Cap Jeunesse in 1995–96 and Polyvalente of St. Jérôme from 1996–1998, Danis was named to the Quebec Junior AAA Hockey League's seventeen-year-old all-star team in 1998–99.

The Bulldogs made the playoffs that year, but they were swept in the first round by the Rochester Americans, as Danis lost all four games of the series.

[17] After one season in the Islanders organization, he signed with the New Jersey Devils as an unrestricted free agent on July 10, 2009.

[20] In the 2014–15 season, Danis belatedly signed as a free agent to a try-out contract with the Norfolk Admirals on November 10, 2014.
