Our history

Our story is that of a passionate person: Rébecca Vandal, an interior designer and multidisciplinary artist whose career is as rich as it is varied. Also a renowned photographer for many years, specializing in capturing the precious moments of motherhood, children and newborns, Rébecca has always been immersed in the world of creation and design.
In 2024, driven by an irrepressible creative impulse, Rébecca decides to give new impetus to her career by merging her diverse talents to give birth to Maison Cosya and the Mini Cosya brand dedicated to motherhood and childhood. This virtual store is not just a place of sale, it is a sanctuary dedicated to the creation of enchanting interior spaces, where every detail tells a story and every element evokes an emotion.
With Maison Cosya, Rébecca and her team aspire to offer their clients a personalized experience where art, design and functionality meet to create environments that reflect the individuality and style of each person.

At Maison Cosya, we firmly believe in the importance of giving back to the community and supporting causes that are particularly close to our hearts. The founder of Maison Cosya, Rébecca Vandal, is also the mother of six children, five of whom have been diagnosed with Autism Spectrum Disorder (ASD). It is this personal experience that has deeply influenced our commitment to raising awareness and supporting people with autism.
We understand the unique challenges faced by individuals and families affected by autism, and we are committed to doing our part to help create a more inclusive and welcoming world for all.
This is why we are proud to give back to Quebec foundations such as the Véro & Foundation Louis and the Fédération Québécoise de l’Autisme, dedicated to supporting autistic people and their families by offering innovative programs and services. These foundations work tirelessly to advance research, promote social inclusion, and provide tangible support to people with autism, and we are honored to be able to contribute to their mission.
Through our partnership with these organizations, we are committed to donating a percentage of our quarterly sales to support their implications. Every purchase you make at Maison Cosya contributes directly to helping young people with autism access the resources and support they need to thrive.
We firmly believe that every action counts and that, together, we can make a difference in the lives of people with autism. Thank you for supporting our business and joining us in our commitment to this cause.
Together we can create a world where everyone is valued, respected and included, regardless of their background or differences.
Thank you for being part of our mission.
