Mar 27, 2026

The Alberta government and the father of a man who suffered cardiac arrest and permanent brain damage after he was allegedly given a “massive overdose” of a potent sedative at a Winnipeg hospital two years ago are suing the facility, three medical providers and two Manitoba health authorities for negligence.

Zachary Hoogerdyk’s father, Edward Hoogerdyk, and the Alberta government are suing the Winnipeg Regional Health Authority and Shared Health, Manitoba’s provincial health authority. They are also suing Concordia Hospital, one doctor and two other medical providers for negligence, the statement of claim filed in the Manitoba Court of King’s Bench last week says.

Zachary, a Calgarian who was 23 at the time, went to Concordia’s urgent care centre with a worsening cold or flu-like symptoms and breathing difficulties during a trip to Winnipeg on March 25, 2024, the lawsuit says.
