A lone gunman went on a shooting spree at Ottawa's transit bus garage on April 6, 1999, killing four people and injuring two others before shooting himself. The gunman, believed to be in his 40s, was a former transit employee who had been laid off and had a history of mental health problems. The incident occurred in the middle of the afternoon, just before rush hour, and the gunman was able to evade police for several hours before being found in the sealed building.

Here is a summary of the source in 3-5 factual sentences:

On April 6, 1999, Pierre Lebrun, a 40-year-old former OC Transpo employee, entered the company's garage in Ottawa and shot five people, killing four, before taking his own life. Lebrun had a history of being bullied and harassed by coworkers due to his stammer, and had previously been fired and rehired after hitting a coworker. An investigation by the coroner's jury found that workplace harassment and a "poisoned work environment" were contributing factors to the tragedy. The jury made 77 recommendations, including 51 directed at OC Transpo, to address workplace harassment and violence. The incident led to changes in legislation and regulations in several provinces, including Ontario, to require employers to take preventative measures against workplace harassment and violence.
