I've ran into this issue before and have found the best solution to
detecting a county is by asking the customer for it via a modal window.

I know some people really like using geo-location, but I've found this
method to be not always accurate. I've found in the US is usually more
accurate than overseas.

Use a public geo-location service:

<cfhttp method="get"
URL="http://ipinfodb.com/ip_query.php?ip=#cgi.REMOTE_ADDR#";
result="response" />

Then use the response XML tree to extract the country or zip:

<cfset xmmm = xmlparse(response.filecontent)>
<cfset countryname = xmmm.response.countryname.xmltext>

<cfif countryname neq "Canada">
<div id=price">#price#</div>
</cfif>

I wouldn't actually do it in this order because of the lag in http
posts. I've had good luck with this method but it isn't perfect
because web services can go down and then your checking system breaks.
If the location service isn't working, then don't allow anyone to use
the module you've built with the integrated geo-location service. Use
cookies as you stated to keep from having to do this every time.
