Why is there almost always Canadian flags in American sports arenas and are there American flags in Canadian sports arenas?

Canadian flags are often seen in American sports arenas as a sign of respect and friendship between the two neighboring countries. This practice is also a way to acknowledge the presence of Canadian teams or players competing in the event. On the other hand, American flags are less commonly displayed in Canadian sports arenas, as the focus is typically on showcasing Canadian national pride. Additionally, Canadian venues may prioritize displaying their own national symbols and flags during sporting events.
