This is my go-to neighbourhood store for outdoorsy stuff, whether it be clothing or shoes or camping gear. I like that it is a local alternative to MEC.
The staff are really great. They will say hello and then leave you alone until you ask for help. And once you've asked, they will take the time to give you lots of pertinent advice. On one occasion I talked with someone for easily 20 minutes about camp stoves.
Something else I really like about Yeti is that they have a lot of Quebec based brands for sale. Its fun to browse something a little different from time to time, and even better if its local.
Finally, I love Yeti for their sales. Many of my pairs of boots, shoes and sandals have come from end of season sales , anywhere from 30-50% off. I've bought clothing on sale as well, but I generally don't have as good luck with finding sizes on sale as I do with shoes.
