Tom becomes the second player the Cougars have recruited from the Giants and he follows his former teammate Sam Crowther to Cougar Park for 2010.
The 21-year-old centre that scored 20 tries in the Giants Reserve Grade during the year also spent some time on loan with Doncaster in the Co-operative Championship in 2009.
Tom becomes the fourth new player to be recruited by Cougar Head Coach Barry Eaton since the Cougars gained promotion by beating Oldham in the Co-operative Championship One Grand Final at Warrington on October 4.
Barry Eaton said: “I’ve been very impressed with Tom. He’s a good six foot tall and very strong.
“I’ve watched him several times and he can do a great job for us in the Championship.”
Burton becomes the fourth new player to sign for the Cougars since the Grand Final victory.
