Cédric Marin

Cédric Marin is a Canadian citizenship and immigration lawyer and the founder of Marin Immigration Law in Ottawa. He works in English and French.

Most of his work today is helping people prove they are Canadian citizens by descent, through a parent, grandparent or older ancestor born in Canada, under the new law (Bill C-3). He leads the firm's team of lawyers and genealogists, and he does the final review and signs off on every citizenship application before it is sent to Immigration, Refugees and Citizenship Canada (IRCC).

He also helps when an immigration application is refused or stuck. If IRCC refuses an application, he can ask the Federal Court to review the decision (a judicial review). If IRCC takes far too long, he can ask the court to order it to decide (a mandamus application). You can see his recent Federal Court cases on CanLII.

He knows the system from the inside. Before starting his own firm, he:

• worked at the Federal Court of Canada as a law clerk to Justice Richard Mosley, helping the judge with immigration cases;
• decided refugee claims and appeals as a member of the Immigration and Refugee Board of Canada;
• worked with the United Nations, deciding refugee cases and recommending refugees for resettlement.

Over his career he has handled hundreds of files, from study and work permits, Express Entry and spousal sponsorship to refused and delayed applications. His clients include families and individuals, schools, registered charities, Canadian tech companies and companies listed on the stock market.

Cédric has been a lawyer in good standing with the Law Society of Ontario (74336V) since 2018, which allows him to represent clients before IRCC.
