American and Canadian IQ test scores

Someone told me recently that he had an IQ of 210. After researching this on the web, as I understood even Einstein's IQ was thought to be between 160 and 180, I see that the American measure is different from the Canadian system. So I guess that accounts for that IQ score. Can you elaborate on that? I have been looking online for any clarification on this, but, apart from the mention of it in the Einstein website, I can't find any info about these differences.

Thanks.
