This is a safety feature - someone tried to access your profile using your user name, but obviously not knowing your password. Now this could have been yourself - after all, you might have forgotten your password. Any attempt to change the password needs to be confirmed - this confirmation is sent to your e-mail account, to ensure only you can really change it.
I checked the IP and found that it belongs to Canada.
No further action required, really - but if you want site staff to research this, I suggest you submit a Support Request.
