Longueuil police confirm that two men forced their way into a Boucherville borough home Wednesday morning but would not confirm the name of the victim.
However, Duhamel's agent Yves Bouchard says it was his client.
Longueuil police say the robbers rang the doorbell of the home and then pushed their way in when it was opened.
Although he was roughed up by the robbers, Duhamel was able to call 9-1-1 after they left and police responded moments later.
The poker player had to be treated in hospital for minor injuries although he has now been released.
His mother told The Canadian Press he is doing well.
Duhamel grabbed headlines in 2010 when he won US$8.9 million in a poker tournament in Las Vegas.
The professional poker player became the first Canadian to win the Main Event at the World Series of Poker with that victory.
Last January, he won the high roller event at the European Poker Tour, taking home more than $270,000 and later won more than $40,000 at the World Series of Poker, bringing his total winnings so far to more than $9.5 million.
Detectives are trying to determine if Duhamel was targeted by the robbers.
Police released a description of one of the suspects but would not give more details, such as whether or not they were armed.
"The investigation is still ongoing," said police spokesman Mark David.
