I just ran the numbers for December, the 1st month of the Cold Weather Emergency Program for 2009-2010. The Rescue Mission has logged 820 overnight stays for the program for December.
This is not 820 different people. Overnight stays represent one person who stays one night. So, for 1 person who stays each night of the month, that amounts to 31 overnight stays. 820 stays amounts to a lot of services provided to people who might otherwise have no place to sleep during the cold.
