Canada and the United States have separate legal systems. If you want the exclusive right to use a name in both countries, you have to obtain trademark registrations from both governments.

To search the USPTO's trademark database, go to TESS and choose a search option. If you are searching for a name, you can use the trademark name search. If you are searching a design mark, such as a logo, you will first need to look up your design code using the USPTO's Design Search Code Manual.

A trademark can be any word, phrase, symbol, design, or a combination of these things that identifies your goods or services. It's how customers recognize you in the marketplace and distinguish you from your competitors. The word “trademark” can refer to both trademarks and service marks.
