The Saint-Jacques Market barely even qualifies as a market. Housed in an impressive and rather massive looking building, the interior is much smaller, but it doesn't feel crowded at all since there are only half a dozen small shops in the whole building. Better than half the retail space remains vacant and it's not hard to see why since customer are few and far between. The five minutes it took me to walk the length of the market space is five minutes I'll never be able to get back.
The one thing that had me visit the market on occasion was Premiere Moisson which has subsequently closed leaving little reason to revisit the place. A few web searches revealed that the building had been converted to office space, but in 2007 the city sold the property to a private developer with the condition that it remain a food market. As it stands now, it's a near complete waste of space and I'd rather see the building converted to condos, at least then the space would benefit somebody.
It's not a farmers market, it's not even a reasonable facsimile of a grocery store. Take a picture from the outside cause it's a cool building, but continue strolling down the street as it's not worth actually stepping inside.
