John Leonard MacKean of Lower Sackville was found guilty in March of sexual assault and communicating for the purpose of obtaining sexual services from a person under 18.
MacKean's crimes date back to September 2012, when a boy who was 16 at the time emerged half-naked from the woods. The boy said he been chained in a cabin and assaulted by three men.
David James Leblanc and Wayne Alan Cunningham fled to Ontario, where Cunningham died.
Leblanc was returned to Nova Scotia, where he pleaded guilty to charges including sexual assault, kidnapping and forcible confinement.
He's serving an 11-year prison sentence.
MacKean said he was invited to the cabin by Cunningham, who arranged for MacKean to sexually assault the boy, who can't be named to protect his identity.
MacKean, 64 at the time of his conviction, had remained free on bail until his appearance today for sentencing.
The communicating charge carries a minimum penalty of six months in jail; the sexual assault charge has a maximum sentence of 10 years.
