Your local Walmart must be pretty big! Amazon currently has close to 2500 employees in the GTA and plans to ship >75% of all products from within Canada by the end of the year.
Majority of those jobs are low end and low paying, but surprisingly Amazon is well reviewed by their employees:

Still ........ I'm a Brick & Mortar guy for most of my purchases. I need to buy a new cordless drill this weekend. How do you get a feel for weight and balance unless you hold it in your hand? How ergonomic is the grip and controls? Can it fit into tight spots? Does the battery pop out easily? I'll pay extra for the privilege.
