On July 1, 2025, a carbon monoxide (CO) leak at Pure Casino Calgary in northeast Calgary led to the evacuation of approximately 300 patrons and staff and sent two individuals to the hospital. Emergency crews, including the Calgary Fire Department and Alberta Health Services, responded around 3:00 p.m. after reports of elevated CO levels, which peaked at 215 parts per million (ppm), a dangerous threshold. The two hospitalized individuals were in stable condition with non-life-threatening injuries, and the casino was cleared for re-entry by 3:50 p.m. after fire crews and ATCO, a utility company, conducted a sweep to ensure safety. The source of the leak remains undisclosed, and Pure Casino Calgary has not yet issued a public statement, though Casino.org has reached out for comment.
This incident highlights the ongoing dangers of carbon monoxide, a colorless, odorless gas produced by the incomplete combustion of fossil fuels, which can cause severe health risks or death if undetected. The swift evacuation and response prevented a more serious outcome, but the event echoes other recent CO incidents in Calgary, such as a fatal poisoning in a Martindale home on June 17, 2025, and an apartment evacuation on June 5, 2025. These cases underscore the importance of functional CO detectors, especially in light of the recent Apollo America detector recall on June 5, 2025, for faulty units. Authorities continue to investigate the casino leak to identify its cause and prevent future occurrences, reinforcing the need for regular safety checks in public venues.
