I know there is a warehouse in Richmond and Mississauga, and I thought those were the only 2 because I've only ever received items from those 2 places. After buying a bunch of stuff for Prime Day, a lot of my items seem to be originating in Calgary. Is Canada Post screwed up, or did Amazon open a new warehouse in Calgary?

September 4 update

I still can't find any official information on a warehouse in Calgary, but there has to be. July 15th was the first time I ever had stuff sent from Calgary, but I figured it must have been something they did for Prime Day only. Since then, I keep getting items from Calgary. Not including the initial Prime Day items, I've had 4 orders ship from Calgary. Being that I live 20 minutes from Calgary, I'm enjoying the speed.

So I am currently working in a fast food joint and currently it is getting worse and worse for me and my coworkers as some management decisions have been making it more and more stressful and toxic workplace. I want to quit soon however because I'm in college atm I need money primarily for college, however due to covid I cant find a job that fits what I'm studying or my certification at the moment. So I'm thinking about getting a night guard certification and work as a night guard or working at the amazon warehouse and I need some advice if the amazon warehouse in Calgary a good place to work at. What I mean is how friendly is the work environment, how are the managers and is it an overall fair workplace?

Thanks guys
