The patient that was being held in isolation at a Toronto-area hospital has tested negative for the Ebola virus.
The early morning announcement came from Ontario's Minister of Health and Long-Term Care, Eric Hoskins, on Sunday.
"I can now confirm a recent case that underwent testing at the National Microbiology Laboratory in Winnipeg was found to test negative for Ebola virus disease," he said.
The patient, who had recently travelled to Canada from Nigeria, went to the Brampton Civic Hospital exhibiting symptoms that could be connected to Ebola, like fever, headache and muscle pain.
Health care workers responded immediately, taking enhanced infection-prevention precautions and had the patient tested.
Hoskins thanked the health care workers and the public health officials who worked on the case and he assured Ontarians that should any cases appear in the province, they are fully prepared.
