Little change was seen in OG images and interest among Americans, but major improvements occurred among Canadians. Differences in perceptions of the domestic and foreign populations towards the host country appeared, confirming earlier research on domestic bias effects. Results indicated hosting the OG contributed to improved images for Americans of Canadians, Canada as a country and as a destination. Canadians evidenced increased pride in their own country. Findings indicated mutual positive benefits for Canada and the OG images and interest.
