Chief Public Health Officer Heather Morrison said Tuesday that a child under the age of 10 tested positive for the virus, but was treated and has fully recovered.
Morrison says enteroviruses circulate every year, with most people recovering at home from the usual mild, cold-like symptoms.
But she says anyone experiencing difficulty breathing or shortness of breath should seek medical help.
In Canada, there have been dozens of confirmed cases of EV-D68 which in a small number of infected children can cause polio-like symptoms.
The illness is being blamed for the death of a four-year-old boy in New Jersey on the weekend.
