Casual employee, wasn’t paid for a shift in February…

…and completely forgot about following up with it. There’s a list of documents you have to fill to be paid for a shift and I kept forgetting to fill them out or just losing them. I know it’s been nearly a year but am I still able to make a claim to get paid for that shift? I have proof of me working the shift, and the credit statement from that week showing that I wasn’t compensated for that specific shift.
