The accused, Federico Jimenez-Martinez, was charged with importing cocaine and possession for the purpose of trafficking after driving into Canada with 18 kg of cocaine hidden in a spare tire.
He claimed duress due to threats from Mexican cartels.
The court acquitted him on the importation charge, finding insufficient evidence of intent to enter Canada.
However, the court found him guilty of possession for the purpose of trafficking, rejecting his duress defence.
The judge found the accused's account of being forced to transport the drugs unreasonable and concluded he was a knowing participant in a drug conspiracy, not acting under compulsion.
