Editorial standards: how we write, review and update our guides

Every guide is published under the name of the person who wrote it, and names its legal reviewer when it has one. The people below write and review our guides today, and the numbers update as guides are published.

When a guide's author is not a lawyer, a licensed lawyer at the firm reviews it, and the guide shows “Legally reviewed by” under the title with the reviewer's name and role. It means the reviewer checked the guide before it was published, and checks it again each time it is updated.

When the author is a lawyer at the firm, the guide does not show a separate reviewer line: the author is responsible for its legal content.

At the end of every guide, an “About this guide” box names the writer, and the reviewer when there is one, shows the dates and links back to this page.

The review covers the guide as general information. It is not advice about your own situation.

When a guide relies on a fee, deadline, form or legal rule, we name the official source: the law or regulation itself, or the government page that sets the fee, so you can check it yourself.

Many guides link straight to those sources. For examples, read our guides on using a US notary in Toronto and on non-compete agreements in Ontario.

Every guide shows when it was first published, and when it was last updated if it has changed since. A guide with a legal reviewer also shows its review, which follows the latest of the two: the guide is reviewed when it is published and again each time it is updated.

When a guide has not changed since it was published, one date covers it: “Published”, or “Published and reviewed” when it has a reviewer.

We use AI tools, and we want you to know how. The tools support the work. The writer, and the reviewer when there is one, are responsible for every guide.

Immigration fees, forms, processing times and business rules change often. When we learn that a law, regulation, fee, form or court decision a guide relies on has changed, we correct the guide, review it again and change its dates.

When we correct a figure in one guide, we check our related guides for the same figure, so our pages do not contradict each other.

In September 2026, for example, we corrected how Ontario notaries are appointed, the premium processing time for an E-2 case filed in the United States, and the fee for the I-94 arrival and departure record.

If you think a guide is wrong or out of date, please tell us. Email editorial@mayo.law with the link to the guide and what you think needs to change. A link to the official source helps us check it quickly.

We check each report against the official source. If the guide is wrong, we fix it, review it and change its dates.

Please do not send private or confidential details about your own case in a correction email. Reporting an error does not make you a client. For help with your own situation, contact us.

Mayo Law practices law in Ontario and New York. Lawyers in both places follow professional rules about how they describe their work, and those rules apply to this website and our guides.

In Ontario, the Law Society's rules require marketing to be true, accurate and verifiable. In New York, this website is attorney advertising under the state's Rules of Professional Conduct, and our footer says so on every page.
