LONDON - Are Canadians easily offended? British tourism officials seem to think so.

New tourism guidelines for the 2012 London Olympics warn that Canadians can be overly sensitive, especially about their national identity.

Seeking to improve the sometimes frosty welcome on offer to tourists, VisitBritain has issued advice on how best to handle foreign visitors.

The advice says Canadian tourists are likely to be upset if mistaken for U.S. citizens.

Britons are also advised to show patience when dealing with guests from India or the United Arab Emirates, and to brush off coarse jokes from Australians or Argentines.

Americans won't hesitate to complain when things go wrong, the guide suggests.

Britain expects about 320,000 extra visitors from overseas during the London Olympics in July and August 2012.
