What is a corporation key?

A corporation key is a password-like credential issued by Corporations Canada to federally incorporated businesses. It was set (or assigned) when your corporation was incorporated, and it's what lets you — or anyone filing on your behalf — access your corporation's file through Corporations Canada's online systems.

It's not printed on your Certificate of Incorporation. It's typically emailed or provided separately at the time of incorporation, and it's easy to lose track of if it isn't stored somewhere deliberate. If you no longer have it, Corporations Canada can help you retrieve or reset it — but it can't be guessed or bypassed, by us or anyone else.

Because a corporation key grants access to file on your corporation's behalf, it's sensitive operational information — closer to a password than a business card. Anyone asking for it should have a clear reason and a secure way to collect it, never over email or an unsecured form.

When Verluma files a federal annual return for you, we ask for your corporation key through our secure client intake form, use it only for that filing, and never include it in emails, confirmations, or any customer-facing document — it's visible only to Verluma staff performing the filing.
