Only a day after police searched the building and employees were led away in handcuffs, Cannabis Culture on Bank opened its doors again Friday morning.
"Everybody (who visited Thursday) was very upset," employee Taryn Morrison told CFRA. "To see us reopen, they were just very happy."
He did not appear to be concerned about police returning.
"I have people smiling at me all day telling me I'm doing a good job. (The police are) the last thing on my mind."
Five people were arrested and several forms of cannabis along with cash were seized on Thursday.
The raid took place at the same time officers swarmed Cannabis Culture locations in Toronto, Hamilton and Vancouver.
The Ottawa operation is not connected with the other police action.
Cannabis Culture founders Marc and Jodie Emery were arrested Wednesday night at Toronto's Pearson Airport.
