The custom duty depends on the value of the gift. If your package was declared GIFT when sending, you get CA$60 for duty free. You have to pay duty for the balance of the value, plus GST/PST, and broker fee.
If your package is small and marked "gift", usually, it won't be charged any extra fee. 6 days is also reasonable. I have met once that my package delayed in one city for 3 days only for custom clearance and it was 8 days for receiving it.
