The 39-year-old was accused of escaping lawful custody, being at large without lawful excuse and fraudulently impersonating another man, a prisoner named Michel Stéphane Boucher.
The escape and impersonation charges were dropped in exchange for the guilty plea on the other charge.
He had been serving a four month sentence for uttering threats against a police officer.
On Friday, Boucher accepted the prosecutor's offer of a 60 day sentence.
Boucher's lawyer, Dimitrios Strapatsas says his client felt the sentence was fair.
"He is happy that he is not being charged with the escape anymore," says Strapatsas.
"Hopefully this will be put to rest and hopefully this time they will verify well his release date prior to letting him go. He knows to check with them and protest a lot stronger than just listening to the guards and go."
Boucher is no stranger to the justice system. A former member of defunct Hells Angels affiliate gang the Rockers, he was previously sentenced to 10 years for gangsterism, conspiracy to commit murder and drug trafficking.
Boucher's father was found guilty in 2002 in the shooting deaths of two prison guards.
He is serving a life sentence in the maximum-security wing of the federal penitentiary in Sainte-Anne-des-Plaines, Que.
