Chrome thinks my site "looks fake" after code-level redirect to other country TLD

Question

I've implemented a code level redirect when someone hits the wrong TLD. i.e. store1.example.com -> store1.example.ca

I do a db query based on the subdomain hit to see which country that store is registered too and redirect to the correct TLD.

Chrome says "The site you tried to visit looks fake. Attackers sometimes mimic sites by making small, hard-to-see changes to the URL"

Anyone dealt with this before?
