I had a long discussion with Michael and Cedric at Marin Immigration Law today. I now have a clearer picture of what I need to pull together to submit my Canadian Citizenship paperwork. They both were very helpful. I am buoyed and also fortified to know how long this process is taking. Thanks so much!

Jeff GGoogle ↗

Cedric stood out as the most straightforward of the immigration attorneys I met with. He made a complicated citizenship process easy to understand and was thoughtful about suggesting ways to keep my legal fees manageable. Very nice guy. Highly recommend.

B HGoogle ↗

I can't recommend Cedric and Michaël at Marin Immigration Law highly enough. My citizenship situation was somewhat complicated (to me) – a multi-generation claim by descent involving Lost Canadians provisions and Bill C-3 – and they took the time to walk me through it clearly rather than just handing me a verdict.

What stood out most was how straightforward and low-pressure they were. They laid out my options plainly: I could file the application myself, or they could handle it for me. No upselling, no scare tactics about doing it alone – just clear, honest guidance so I could make my own informed decision.

If you're navigating a complex Canadian citizenship matter and want a firm that respects your intelligence and your choices, I'd point you straight to Marin Immigration Law.

Seraphine MGoogle ↗

Larry MGoogle ↗

My consultation with Chanelle was informative and straightforward. She spent extra time to answer my questions and afterward sent me email follow-up with helpful links to assist me in finding elusive documents. Very positive experience. I will be moving forward with Marin Immigration Law to handle my Canadian citizenship applications.

Nancy LGoogle ↗

We highly recommend Cedric Marin at Marin Immigration Law for Canadian citizenship by descent applications. He was extremely helpful, knowledgeable, and shared many valuable tips to make the process much easier and avoid common mistakes. Since we had already completed much of the genealogy work, he offered flexible service options rather than trying to sell us services we didn't need. His honesty, professionalism, and client-focused approach were greatly appreciated. A true pleasure to work with.

Michael HGoogle ↗

I met with Cedric for a 30 minute consultation to review my application for a Canadian citizenship certificate under Bill C-3 (Canadian citizenship by descent). He was able to give me a huge amount of info in a short period of time, as well as clear recommendations and next steps for my situation. I'm so grateful for the opportunity and a huge thanks for noticing a critical issue with one of my primary documents. This was super helpful and well worth the cost. Anyone applying for Canadian citizenship under C-3 should consider a consult with Cedric!

Doug WGoogle ↗

Cedric was really helpful in providing information to make my application for Canadian citizenship by descent helpful. Although I did a lot of research, Cedric was able to point additional sources as well. Thank you Cedric!

Mark SGoogle ↗

Cedric was straightforward and honest about our case. He was kind and friendly and made me feel like he would do a good job at our attorney.

Annette PGoogle ↗

My experience was better than expected and exceeded my expectations 100%. Making the appointment online was easy. I was excited to meet with Mr. Marin to further discuss my situation but I had overlooked the time difference and missed my virtual meeting! Mr. Marin could not have been more kind and understanding. He quickly responded to me and was able to be flexible with his schedule and we completed the virtual meeting later that day. I feel very confident in knowing I will be in good hands.

Joseph EGoogle ↗

I had a single consultation with Cédric Marin, and he made the most of every minute. After quickly getting up to speed on my situation, he gave me clear, practical advice on how to move forward with my claim – no fluff, just genuinely useful guidance that saved me time. Highly recommend for anyone who wants a straightforward, efficient consultation.

Renaud STrustpilot ↗

I worked with Cédric on my Express Entry PR application and had a very positive experience throughout the process. What stood out immediately was how quickly he understood my case and structured the application in a clear and effective way. His approach is very diligent and detail-oriented, which made a real difference in how the file was prepared. He was especially thorough during the final stages, ensuring all documents were consistent, aligned, and properly reviewed before submission. This level of precision gave me a lot of confidence throughout the process. Thanks to his professionalism and strong understanding of the immigration landscape, my application progressed smoothly and reached the portal stage (P2) in only 3 months from AOR. Beyond the technical side, what really stood out was his level of involvement and dedication. He genuinely cares about doing the right thing for his clients, and you can clearly feel the energy and commitment he brings. I would definitely recommend his services to anyone going through Canadian immigration, especially if you are looking for someone who is both highly knowledgeable and truly invested in your success.

Caro RGoogle ↗

Cedric is a phenomenal professional. He helped my husband and I put together a strong application for spousal sponsorship/permanent residency. He was thorough with his feedback and was always prompt, kind, and helpful in his communications. I highly recommend working with him.

Andree BGoogle ↗

Cederic was incredibly helpful, expert in his knowledgeable of Canadian immigration law, and practical in his advice. I would not hesitate to work with Marin Immigration Law again.

Ismaila BTrustpilot ↗

I had my first immigration consultation with this attorney and I was extremely satisfied with the experience. He was very attentive, patient, and truly took the time to listen to my situation from beginning to end. What I appreciated the most was how clearly he explained everything and made sure I understood all the important details regarding my case. He also provided helpful resources and links that will guide me through the next steps of my process. It’s clear that he is very knowledgeable and professional. I highly recommend him to anyone who needs reliable immigration advice. One thing that impressed me even more was his honesty and professionalism. I originally booked a one-hour consultation, but our session ended earlier. He kindly refunded the remaining time that we didn’t use, which I found very generous and truly professional. Don’t hesitate to reach out to him, you will be in good hands.

Ro ZGoogle ↗

I had a very positive experience with Cedric. There ended up being a technical issue with a scheduled consultation appointment. Rather than letting the situation go unresolved, he personally reached out to make sure everything was addressed.

What stood out most was how professional and kind he was throughout the interaction. He made it clear that he takes client communication seriously and didn’t want anyone to feel that their inquiry had been overlooked, which says a lot about the way he approaches his practice.

Melissa BGoogle ↗

Cedric is a wizard of Canadian immigration. His depth of knowledge and understanding are spectacular. He is friendly, efficient, very helpful, and realistic. I now have homework and a road map to follow thanks to information and follow-up email from his valuable phone call. Many thanks.

Philip MGoogle ↗

Cédric is the consummate professional. He creates macro-level strategies, including the value-add of engaging a skilled genealogist to contribute to my citizenship application, while remaining attentive to each and every relevant detail.

Being as kind and considerate as he is regarding interpersonal engagements, Cédric is in fact “the complete package” in the realm of immigration law. A five-star rating isn’t sufficient acclaim for his work – if you need professional support in this area, Cédric is the man to see. It’s that simple.

Ella JGoogle ↗

I do not often leave Google Reviews, but Cedric was so incredibly helpful. He's knowledgeable and a great communicator.

How we find your records

  • We trace your line generation by generation and find the record that proves each link
  • We order the records for you and follow up until they arrive
  • We read French parish and civil records in the original
  • When a record is missing, we build the proof from other records
