Dean is 19 and has already spent the better part of three years with the Hull FC first-team.
“I’m looking forward to getting the opportunity to represent the Toronto Wolfpack, and I cannot wait to get out to Canada and get started!” Dean said.
Toronto coach Paul Rowley was particularly enthused by what he feels is a key signing, not only for now, but for the future of the club.
“I’m delighted to have a young talent like Reece on board.” Rowley said.
“I see Reece as a future star in our game, and I look forward to working with him to help him reach his full potential.”
