Behind a paywall, here is the only part I can read.
OTTAWA—In early 2019, during the final months of Charles Bordeleau’s seven-year term as Ottawa police chief, an inspector for the city’s downtown core came to him with a problem: Things were getting out of hand at the McDonald’s, the inspector told him. He didn’t have to say which one. It was long past time for an intervention.
For years, the 24-hour fast-food restaurant on Rideau Street, a main drag in the heart of downtown Ottawa, had been a last stop for bar-district leavers seeking greasy fare to soak up the booze. At any time of day, the McDonald’s was a wild card, but after midnight it could be pure chaos. It smelled of French fries, beer breath and warm bodies coated in dance-club sweat. Often, there was no discernible lineup in front of the service counter, just a mosh pit of people hungry for cheeseburgers.
