Three accused were tried for various drug-related offences following a controlled delivery of a package containing cocaine imported from Suriname.
The package was intercepted by the CBSA and picked up by Williams using fake identification.
Williams transferred the package to Allen, who fled from police.
Nwankwo was later arrested reaching into the trunk of Allen's car where the package was stored.
The court found Williams not guilty on all counts, as the Crown failed to prove he knew the package contained cocaine.
Nwankwo was found guilty of conspiracy to possess cocaine for the purpose of trafficking.
Allen was found guilty of conspiracy to import, possession for the purpose of trafficking, and conspiracy to possess, but not guilty of a separate possession charge relating to cocaine found in his residence.
