Netfirms Canada moving hosting to US location

I just got an email from Netfirms saying they are moving the physical location of their hosting from Canada to US…Now this will be no big deal for most, however, if you are a Canadian company and want the best results in the “Canada Only” search results, having a Canadian IP number helps…

With this move, IP numbers will now be in the US range…So someone using the “Canada Only” method may no longer find you at the place in the results as before this move…

This comment is based on my understanding of how the search engines work…Does anyone else think this or have other information that will be helpful?..
