Ottawa Public Health confirmed a second case of E. coli in the Ottawa region Friday.
Officials have not released many details on the case, but confirmed the illness is linked to the outbreak in romaine lettuce that is hitting Ontario and Quebec.
CTV News found out about the first case earlier this week.
Both Ottawa patients are under the age of 65.
Public health officials have told the public to avoid eating romaine lettuce until further notice.
The Canadian Food Inspection Agency (CFIA) said it has tested 2,000 samples of fresh lettuce and packaged salads but did not find any e coli contaminants.
Aline Dimitri, the deputy chief food-safety officer for the CFIA, told the Canadian Press that the test results do not mean E. coli is gone from Canada's food supply, but that the bacteria is at "very low levels."
Three more E.coli cases were confirmed Friday across the country, bringing the total patient count to 22.
