In deciding to raise the level of travel advice, we take input from a wide variety of sources. We look at the local circumstances on the ground, the reports of the mission, the consular caseload and trends that we see. We also consult with other partners who have different information on what's happening in the region, and we use the criteria for the different levels to apply the levels of risk.
It's evaluated on a 24-7 basis. Updates are made throughout the night. For example, in cases of natural disaster or sudden emergencies, it's very important that Canadians have that information as quickly as possible, so we are continually reviewing the travel advice for all countries. We look at specific regions within the country so we can target advice in areas of a country that might be, for example, at a higher level of risk than others.
