Canada will face a serious teacher shortage in the next 15 years due to the aging of its teaching work force. A study of patterns of teacher supply and demand in British Columbia (Canada) interviewed key informants at the Ministry of Education, British Columbia College of Teachers, and British Columbia Teachers' Federation, and board officials and union presidents from 12 school districts. Findings include the "Canada Goose Syndrome"--rural teachers leaving isolated, rural school districts to pursue teaching careers in the south of British Columbia. These migrants are responding to the needs of urban school districts that are experiencing massive retirements. This syndrome will exacerbate the situation in rural school districts, which are already experiencing shortages of qualified teachers. Recommendations include providing financial and other incentives to rural teachers, opening a university in northern British Columbia, and linking years of experience with financial incentives. Other research indicates that the United States, Australia, and New Zealand have similar experiences. (TD)
