Good Earth Coffeehouse and Bakery has launched a sweet holiday campaign to help people in need of housing. All Good Earth’s 15 Calgary locations and one in Okotoks are selling seasonal packages of gingerbread families — two adults and one child. The package sells for $5.95. One dollar from each sale will go to Habitat for HumanityCalgary. Habitat for Humanity is a notfor-profit organization that helps families with low incomes get into home ownership.
