A slightly higher number (6,000 to 22,000) are what they call "episodic homeless." These are people who move into and out of homeless shelters multiple times over several years.
The vast majority of Canada's homeless (176,000 to 188,000) are "transitional homeless" — individuals and families who enter the shelter system for a short stay of generally less than a month. For them, homelessness is usually a one-time event.
Even though the first two groups make up less than 15 per cent of the homeless population, they account for more than half of the resources of the homelessness system.
