Mec is a Candian version of REI
The bag is known as the 'Vancouver handbag' mec shoudler bag

That and the soft briefcase are so common north of the border that Canadian airports now accept them as proof of residency - if you are wearing goretex and carrying one of these you can bypass the passport check.

Most of canada is pretty sensible, wearing hiking gear and heading into the woods with one of these is fine. Although I probably wouldn't EDC one in my briefcase.
