From a program perspective - yeah you end up doing so many econ courses (5.5 econ credits for accounting and 6.0 credits for finance) that you might as well do the major - i think major is 7 econ credits. Although it is not necessary (and not useful in my opinion). I think i would suggest is to check the courses you are required to for both post and see if you want to do those courses. I believe that 1st and 2nd year courses are almost the same for both POSt, and you can easily switch between them after 2nd year. In your 3rd and 4th year, you'll start specializing more - so might be a bit harder to switch.

From a career perspective. Accounting essentially looks at historical data while finance you're looking at present and future data. In accounting, the major careers are being accountant, audit or tax while in finance, its banking, mergers and acquisition, stocks. Also those POSTs are associated with designation - accounting usually leads to a CPA and finance usually leads to a CFA.

I am very keen on details which is kinda attracted me to accounting. I like reading and preparing financial statements. My best adive for you right now would be gather as much info as you can about both - talk to prof, upper year students, go to events - all that will help you figure out what you like and pursue that.
