Currently, Apple sells refurbished iPhone 6s and 6s Plus handsets with 16 and 64 GB storage in various colours, with the entry-level Rose Gold iPhone 6s retailing for USD $449, $100 less than the current pricing for a new handset of $549. The refurbished iPhone 6s Plus retails for $529, which is $120 less than the $649 price you’d pay for a 32 GB model new.
All these handsets are unlocked and SIM-free, so you can use them with your preferred carrier, and they are covered by Apple’s one-year limited warranty, as well as the 14-day returns policy. As noted by Apple, refurbished iPhones have a new battery and outer shell, and come in a new white box.
Of course, if you want to extend that limited warranty, you can do so by buying AppleCare+.
The recent update of the US online refurbished store could easily suggest there is hope that Apple will also make refurbished iPhones available in Canada, although there is no guarantee of that. We’ve seen Canada somewhat neglected in terms of services Apple has made available in other parts of the world (I know you can think of some.)
