NUANS Corporate name search
Use this corporate name search tool to compare your proposed business name to those of existing corporations and trade-marks.
You will need a NUANS report to incorporate your business federally, and to incorporate in most provinces and territories as well.
The cost of creating your own NUANS report is $21.47 plus applicable taxes. The cost of requesting assistance to create a report varies.
Currently, the province of Quebec does not provide data for NUANS. If you are doing business, or plan to do business in the province of Quebec, you should search Quebec's Enterprise Register, Quebec's database of corporations.
