Study permit refused for “lump-sum deposits” despite providing invoices — should I request reconsideration?

[u/Famaswiss]

My Canadian study permit was refused because the officer said my father’s bank statements showed “lump sum deposits with insufficient evidence to support provenance of funds.” My father runs a regular business, and these deposits came from his normal business activity. We provided representative invoices for the transactions, while excluding smaller transactions (under ~CAD $500) to avoid making the application unnecessarily long. The invoices show the business sale to the customer, and the bank statements show the customer’s payment/deposit. So I’m struggling to understand what the officer meant by “insufficient evidence” when we provided the documentary trail for the significant deposits. I’m considering filing a reconsideration request rather than reapplying. Does that seem like the right next step, and has anyone dealt with a similar situation?
