MONTREAL For businesses along part of St. Laurent Blvd., the timing of the news they got recently couldn’t be worse. The city is planning to rip up a stretch of sidewalk in Mile End, and while normally that’s business in usual in Montreal, the businesses affected say they wish they could get a reprieve. They won’t be able to open their all-important terrasses until partway through the summer season, when every penny right now counts. It’s a “massive impact on us” at this point in the pandemic, said Stephen Kamp of Sparrow Bar and Cardinal Tea Room.
