I have a Phantom 3 Advanced drone with barely any flight time, also a quality backpack I bought off of Amazon. What's some of the ways I can sell this in Canada, apart from Kijiji. Do any big box stores buy used drones? Any advice would be appreciated!

Big box stores probably won’t buy used items. The best way would be a local online community sale site where you can list it. eBay is also a good place.

In Canada https://canada.dronetrader.com has a fair number of used drones listed. It is also free to list on that site and they don't take a commision.

Since any advice would be appreciated, my advice is to keep it, unless you're getting out of the hobby.  You won't get the value of it by selling it.  And there are tons of great reasons to have a second drone.  

May I ask why you are drifting away from your Advanced?

You can advertise it here:

Gives you an idea of what others priced theirs around.

Good luck.
