Where would a Canadian on-line seller get third party shipping insurance?

I’ve been selling on-line and realise that I should get shipping insurance in case my items are lost or stolen while in transit to buyers.
US sites recommend third party shipping insurance but some quick searches in Canada come up empty.

I suggest that you use the freight forwarder/shipping company for this type of insurance.

When I buy on-line, I usually pay for the shipping and insurance, and he seller just arranges the delivery.
