The accused, a 24-year-old Antiguan national, pled guilty to importing 4,322 grams of cocaine into Canada concealed in false-bottomed suitcases.
She travelled with her three-year-old daughter and co-accused Teesha Thomas, who was also carrying cocaine.
The accused was arrested at the border and has been in pre-trial detention since May 9, 2015.
The Crown sought seven years imprisonment; the defence sought five years.
The court imposed a sentence of 66 months (5.5 years) imprisonment, with credit for 223 days of pre-trial detention at an enhanced rate, resulting in a further 55 months to be served.
The court also imposed a DNA order, a 10-year firearms prohibition, and a $200 victim fine surcharge payable within two years.
