Via the Government of Canada: Ebola Outbreak in West Africa. Excerpt:
The Public Health Agency of Canada (PHAC) recommends that Canadians avoid all non-essential travel to Guinea, Liberia and Sierra Leone due to the ongoing Ebola virus outbreak.
This recommendation is designed to protect Canadian travellers and make it easier for health officials in these countries to dedicate their resources towards controlling the outbreak.
Although the risk remains low, travellers could face difficulties accessing health care services from an increasingly burdened health care system. Travellers could also be exposed to the Ebola virus when seeking medical care in a health care setting.
Canada is not alone in making this recommendation; several other countries are also recommending against non-essential travel to the affected countries.
