Although it won't help you for 2016, if you're running an Anchor store, you'd be well served to invest in at least some basic accounting software (Quickbooks is the obvious one, and has different levels for different needs, but there are many others).
It's a relatively minor one-time investment when weighed against all the hassle, loss of time, and frustration of sorting through eBay/Paypal, etc. records. While it does require daily (or at least regular) input of your sales, expenses and other data, the great advantage is that you'll be able to see how your profits and expenses are trending at any point in the year and make necessary adjustments to your business plan accordingly. I think that is vital information to have. And you'll have all your data in one place to automatically generate the figures needed for income tax filing.
The alternative is to do as some here have suggested and use the CSV downloads from eBay and Paypal. This is more unwieldy than accounting software, but again, you'll at least have all your figures in one place. If you're creative in using Excel's built-in features, with CSV charts you can actually design your own simple extrapolated summaries from the data to give you an always-current snapshot of your profit and loss status, expenses, and income.
The bottom line is that if you're running a business, no matter how small, you really need to have your own records, in some form or another. Don't rely on eBay, Paypal, etc. to keep your business records for you. For one thing, their data could crash. For another, you have no control over that data and where or how long it's kept. Incidentally, as a business, Revenue Canada does require you to keep records, which I don't think is fully satisfied by having the data stored by eBay/Paypal. And if you're ever audited, you'll need to have your own records at hand.
Personally, because I'm old-school (i.e. BCE -- "Before the Computer Era"), I subscribe to the belt-and-suspenders principle of record keeping -- I keep a hard copy printout of the details of each sale, and enter the data on a (relatively simple) accounting programme. This saves a lot of grief come tax time. If you don't keep paper copies of your records, a weekly backup of your business data onto a jumpstick (or wherever) is a very good idea. With our daily and almost total reliance on computers, it's easy to forget that the carriers (computers) can still crash and digitally-recorded information can be lost.
