Canada is tightening border and immigration measures after a rise in Ebola cases in parts of central and east Africa.
The federal government says the steps are aimed at limiting any potential spread of the virus as outbreaks continue in the Democratic Republic of Congo, Uganda and South Sudan.
From this week, travellers arriving from the affected countries will be required to isolate for 21 days.
Officials say the changes are being introduced under the Quarantine Act and take effect on Saturday.
They stress the risk to Canada is currently low and that no travel-related cases have been detected.
