The House Finch naturally expanded into British Columbia in 1935 from its native range in the western United States. An introduction to Long Island, New York in 1940 resulted in another range expansion throughout eastern North America, and the species is now found more or less across southern Canada, having reached Ontario, Quebec and the Maritimes in the 1970s, and parts of the southern Prairies in the 1980s and 1990s. Many individuals are resident, although seasonal movements of varying distances occur in some regions. There are approximately 160,000 individuals in Canada, which represents 0.4% of the global population and a very low degree of responsibility for Canada. The Canadian population of House Finch has shown a moderate increase relative to 1970 based on the Breeding Bird Survey; confidence in this assessment is high based on good coverage and high precision in the trend. However, the population has declined enough since its peak in the 1990s and early 2000s that it is now slightly below its goal range.
