It's been exactly one year since the first known case of COVID-19 was detected in Canada.
The 56-year-old man had arrived at Sunnybrook hospital in Toronto with what seemed to be mild pneumonia.
But because he had travelled from China and his X-rays were unusual, the decision was made to admit him.
Samples were sent by taxi to Ontario's public health laboratory, which had been working to come up with a reliable test.
The lab was soon able to confirm the man was infected with what was then being called the novel coronavirus.
Although ``Patient Zero'' eventually recovered, more than 19,000 people in Canada have since died from COVID-19.
Beyond the physical, mental and economic devastation that was to follow, the virus prompted a social upheaval that would fundamentally alter the lives of millions of Canadians.
