NUANS Report

NUANS stands for Newly Upgraded Automated Name Search. It is the Government of Canada's corporate name and trademark search system, operated by Innovation, Science and Economic Development Canada. A NUANS report compares a proposed corporate name against federal and provincial corporate names, registered business names and Canadian trademarks, and returns the entries that are identical or similar.

The report is evidence, not a decision. Ontario's incorporation notice describes it as a list of existing corporate and business names, as well as trademarks, that are the same as or similar to the proposed name, and makes the incorporator responsible for reviewing it. Corporations Canada states that getting a NUANS search does not mean the government has approved the name.

A finished report shows the proposed name, a reference number, the search date, the jurisdiction the search was weighted toward, and the matches grouped as exact, similar and trademark hits. Our long-form NUANS report guide explains how to read each group.

Ontario. A corporation incorporated under the Business Corporations Act with a word name must be supported by an Ontario-biased or weighted NUANS report. A Canada-biased report is not accepted. The report cannot be dated more than 90 days before the articles are filed; the corporation keeps it at the registered office and enters the reference number, searched name and date in the online filing. The Ministry does not run the search; registered search houses and law firms with a NUANS membership order it. The same type of report supports articles of amendment that change a corporation's name.

Federal. For an online incorporation or name pre-approval under the Canada Business Corporations Act, the search is built into Corporations Canada's Online Filing Centre, so no separate report is ordered. A standalone report is still required for a federal revival or amalgamation, and a pre-approved name is valid for 90 days.

Numbered companies. A number name needs no NUANS report in either jurisdiction. See named vs. numbered corporations.

An identical Ontario corporate name will generally block an Ontario filing unless the specific conditions for using it, which can include a legal opinion, are met. Punctuation changes do not make a name different; adding or removing a word, numeral or initial, or switching the legal element, can. Similar names are the incorporator's risk: the Ministry does not vet similarity, and a confusingly similar name can lead to a names hearing or a lawsuit after incorporation. Corporations Canada examiners compare federal word names against the search and may ask why confusion is unlikely.

The report is not trademark clearance. A corporate name creates no trademark rights, and the owner of an earlier mark can force a rename regardless of what the registry accepted. It is not a business-name registration, which is a separate filing under Ontario's Business Names Act for any operating name. It does not reserve exclusive rights: the proposed name is noted in the NUANS system for 90 days so other searchers see it, but that is notice, not ownership.

An Ontario filing must be made within 90 days of the report date, with a buffer, because a report that expires before the articles are endorsed must be replaced. Report fees are set by the search house or, for federal filings, through the Online Filing Centre, and vary; the government incorporation fee is separate.

Before paying for a report, run free screens: the Ontario Business Registry, Corporations Canada's federal corporation search and the Canadian trademarks database. Lamba Law's free business name search tool adds an AI-assisted web screen for existing businesses, competitors, obvious trademark conflicts and domain availability. It is a preliminary step, not a NUANS report and not a legal opinion.

Priya wants to incorporate "Lakeshore Analytics Inc." in Ontario. A free registry search finds no identical corporation, so her lawyer orders an Ontario-biased NUANS report. It lists a dissolved "Lakeshore Analytic Services Ltd.", an active "Lakeshore Analytics" business name in another province, and a registered trademark for LAKESHORE in financial services.

The registry is unlikely to refuse the name on the dissolved match alone, but the trademark is a real problem if Priya's business touches financial data, and the out-of-province business name signals a competitor she would be confused with online. Her lawyer recommends a more distinctive name before filing, and the corporation is still incorporated on schedule.
