Netmatrix highly recommends you register ALL the Global Top Level Domains {gTLD} (.ca .com .net .org .biz .info .name .us) versions of your domains.
Here the list of Global Top Level Domains we can register for you.
If you only register the .ca and/or the .com version of your domain name. One of the largest scams on the net is domain name extortion (and it's legal).
It works like this, you register YourDomainName.ca, but you do not register YourDomainName.com. These domain name scammers register YourDomainName.com to themselves and try and sell it to you for $500 - $1000. If you don't buy it from them, they point it at a porn site (or something worse). Then when you want to buy it, the price is much much higher.
Companies/Individuals registering the .com .ca .net .org .biz .into .tv (the versions you haven't register) versions of your domain name and pointing that domain at a not so nice website (ie Porn or something worse) and then charging you $1000 per domain name to selling the .net .org .biz .into .tv version of your name back to you at this inflated rate. We've heard of one scam artists charging as much as $10,000 per domain name.
There is a domain name dispute resolution legal procedure that a company can use to get back their domain names that someone else has registered. That process takes months and can costs tens of thousands of dollars in legal fees. Depending on the domain name in question it's cheaper and faster to pay the scammers than to go through the domain name dispute resolution legal procedure.
The .ca and .com covers 90% of the people trying to get to your website. The reason you would want to register these other versions of your domain name is if your worried about someone registering them and putting up a bad website under your name.
If your are a publicly traded company or have trade marks to protect, we are recommending to our customers if they are at all worried about public identity, image or brand recognition and someone pulling this domain name scam on them, you should register the .com .ca .net .org .biz .info versions of your domain name just to be safe. If you plan on doing business in the United States or Great Britain we also recommend you register .us and .co.uk. It's way cheaper than paying the scam artists.
