India Post — speed post has been stuck at canada customs for 10 days

My courier (Tracking no: eu[protected]in) is stuck with canada toronto-a custom hold and extra information are showing as "awaiting presentation to border agency/s" since 1st december, 2019.
The tracking shows awaiting presentation to border agency/s. Its been almost 10 days since the packet reached canada via india post. It is a very important document. Why is it taking so much time to clear customs? Kindly resolve the issue at the earliest!
