You can buy an unlocked Galaxy S7 in Canada

Samsung isn't one to rock the boat when it comes to its relationships with the largest carriers in the country. But for the new flagships they're making a bit of an exception and are offering unlocked versions of its new Galaxy S7 and S7 edge. But to get your hands on these, you'll need to buy them at the company's Experience Stores located at Toronto's Sherway Gardens, Burnaby's Metrotown Mall, Richmond Centre Mall, or West Edmonton Mall. When you buy from these stores you'll get two unlock codes (in case one of them doesn't work), and a Gear VR as well as 128GB microSD card (just to remind you that expansion is once againa available on the S7).
