The first place on the right is a convenience shop - in Quebec City, these were often called "Accomodations" - on the hand lettered sign in the window, it was shorted to 'Acc. Louis' ( I think). The next shop is a casse-croute (snack bar).
Here's how it looks today - big change!:
This was about the time the Gabrielle Roy library opened - I think it helped to revive the neighbourhood - there used to be few public libraries in the predominantly French speaking areas of Quebec. In 1901, the Catholic Archbishop of Montreal, Paul-Napoléon Bruchési, stopped Montreal from having a library donated by Andrew Carnegie, even after the municipal council accepted it, because books that the church disapproved of would be available.
