A B.C. man who admitted his role in supplying drugs to Yukon dealers was sentenced Wednesday in Yukon territorial court to three and a half year in a federal penitentiary.

Matthew Truesdale of Courtenay, B.C. was arrested in November 2013 as part of a bust police called one of the most significant organized crime investigations in Yukon — "Operation Monolith."

Truesdale and Asif Aslam, also arrested in the bust, arranged to send 1.7 kilograms of cocaine to Yukon through a longtime Whitehorse drug dealer. That dealer had become a police agent not long before, and immediately turned the drugs over to police in Surrey, B.C.

Both Truesdale and Aslam pleaded guilty to trafficking cocaine, last November. Aslam is due to be sentenced next month.

Truesdale's lawyer Doug Jevning submitted several letters to the court, from Truesdale's employer in B.C. and several friends. The letters express support for Truesdale, and some say the convicted drug dealer is not the man they know.

But Judge John Faulkner rejected a suggestion that Truesdale had simply made "poor choices," saying the crime was more serious than that.

Truesdale was given eight months credit for time served, meaning he'll spend another two years and 10 months in prison.
