The first break-in took place May 22 at the second floor rental offices above the market, where vendors manage their money and paperwork.
"The very first thing I heard was my neighbour freaking out because she was robbed again for the second time in that five day period," Joan English, manager of the Petit Ami coffee shop in the market told CBC News.
English said that while her own office was simply rifled through with nothing taken, others had their safes broken into, with money and laptops stolen.
According to English, the Canadian Mortgage and Housing Corporation (CMHC) that manages the building failed to take any action following the initial break-in.
"The only people that are talking about it are the people who have been affected," she said. "There's been no behavioural change from the security company and CMHC doesn't seem to care about it as much as we do."
CMHC spokesperson Lisa Ono said the company could not comment on the situation.
"The Vancouver Police Department is actively investigating and we don't have any further information to share at this time, " she said.
Vancouver police say a suspect has been identified, but no arrests have been made.
