Sweden has its own populations of Canada Geese. But I didn't know that they are a recent introduction to Sweden, as recently as 1929:
Canada geese have also been introduced in Europe, and have established populations in Great Britain, Ireland, the Netherlands, Belgium, France, Germany, Scandinavia, and Finland. Most European populations are not migratory, but those in more northerly parts of Sweden and Finland migrate to the North Sea and Baltic coasts.[21] Semitame feral birds are common in parks, and have become a pest in some areas. In the early 17th century, explorer Samuel de Champlain sent several pairs of geese to France as a present for King Louis XIII. The geese were first introduced in Britain in the late 17th century as an addition to King James II's waterfowl collection in St. James's Park. They were introduced in Germany and Scandinavia during the 20th century, starting in Sweden in 1929.
But they are migrant, so where do they go in Winter? The same post in Wikipedia https://en.wikipedia.org/wiki/Canada_goose also explains that they migrate to the Baltic and North Sea coasts, where they overwinter, then returning they way they came in the Spring. I does not specify where in Sweden and Finland they go in the summer.
I occasionally see Canada Geese flying west in the autumn, flying in V-formations. There is even a picture on the Wikipedia website of geese walking in the V-formation. It is a remarkable sight watching geese migrate, and hearing their cries.
