Saskatoon / 650 CKOM Jan 18, 2021 3:20 PM Dr. Mark Wahba receives the Saskatoon Fire Department Award of Merit on January 18, 2021. (Saskatoon Fire Department/Facebook) Dr. Mark Wahba knew something wasn’t right when he had two patients seek help at Royal University Hospital last Thursday. The emergency medicine physician’s two patients were complaining of headaches, alerting him their dog was also sick. The pair lived in an apartment building and, after noticing the signs, Wahba acted quickly. He called the Saskatoon Fire Department directly and firefighters were dispatched to the apartment building to find dangerously high levels of carbon monoxide within the facility.
