e-file of Canadian immigration

Has anyone encountered such a problem of wrong address posted by immigration officer online?
I submitted my application to Buffalo for Canadian immigration and got their letters at my address (which is the correct one), but when I checked my file status online from CIC website, they got the country wrong. They put me in Canada, but I am in USA currently. The street name, city, state I am in are correct. Should I mail them to correct this mistake? Will this influence their correspondence with me in the future?
