They would need the template if that was the way they chose to do the cheques, and not order them. Apparently you can buy cheque stock paper, like business cards, etc. and use word to print out cheques, from there, you can use QB's to fill in the cheque.
From what I could find in QB's, I don't think you could just print a cheque without having the pre-made blank cheque, with account number, business name, etc. But maybe it can be done.
I have no idea who testified to missing cheques either, possibly Dugal? I know I have read posts referencing it, but didn't know if it was in testimony yet or not.
