This may be a dumb question, but here goes.....
Is the fee an annual fee for all units sold, or is the fee per unit sold?
This is from the Health Canada site:
Section 12(1) of the Fees in Respect of Medical Devices Regulations sets out the following table of fee based on Annual Gross Revenue
Annual gross revenue from the medical device.
1 Less than $20,000 the fee is $50
2 $20,000 or more the fee is $100
Section 12(2) of the Fees in Respect of Medical Devices Regulations states, "The fee set out in column 2 of Item 1 of the table to subsection (1) must be accompanied by a statement, certified as true and correct by the person responsible for the manufacturer's financial affairs, declaring that the annual gross revenue for the applicable medical device was less than $20,000."
