About us


Art Conservation is one of the most integral aspects for the preservation of our cultural history. Art, of any form or medium, is a creation of mankind from the time they were able to use their hands until today.

Art Through History

Artwork reflects the period in which it was created; it reveals the different faces and shapes of history and it exposes its creator’s emotional state. These objects we call art have been, and continue to be, passed on from generation to generation as humans carry on with beautifying their environment. With the proper care and preservation, artwork will outlast us all as we pass them on to the future.

Art Conservation

As art conservators, we understand the obligations and responsibilities that we have in order to preserve history through art and we do so professionally and in accordance with the International Conservation Code of Ethics. In our establishment we will make every effort to address all the concerns you might have regarding the conservation of art, including costs, and guide you when making a decision that will prolong the life of your heirlooms.

Over 40 Years

With over forty years experience working with public institutions and galleries both in Canada and in Greece, we have a deep knowledge and understanding of Art History and we treat all art with the same respect and care. At XC Art Restoration, we specialize in the conservation of fine artwork and objects, as well as the proper conservation grade framing and design.

Our Team

It is very important to be able to trust the professionals with your heirlooms, therefore, a general knowledge of the conservators involved, and their background is necessary. Whether you choose our establishment or another studio to perform the art conservation work on your paintings or objects, it is imperative to know the qualifications of the people who will be working on your works of art.

Art conservation is a process that demands the highest form of professionalism, ethics, as well as a tedious and methodical approach. Each painting or object has its’ own character, its’ own challenges and therefore requires an individual treatment. In the past, art conservators would focus on beautifying paintings, which usually involved overpainting, and unfortunately in many instances took away from the authenticity of the piece being restored. Conservators today are more concerned with preservation and longevity rather than aesthetics and that is the methodology that we practice here at XC Art Restoration.

Co-Founder, Art Conservator

Kostas Xenarios studied art conservation at the studio of the Athenian Technological Institute, under his Italian educated professor Stavros Baltoyannis with emphasis on the preservation of artwork. Kostas’ schooling was in art conservation, yet his preference lies within conservation of paintings regardless of their medium. From 1969 to 1974 he worked for the Greek Ministry of Culture on the Island of Crete, restoring Byzantine frescos and icons in monasteries and churches. In 1974 he immigrated to Canada and settled in Toronto where he has been living and practicing his talent in art conservation ever since. He has worked for several galleries and public institutions, including the Royal Ontario Museum and the Historical Board. Kostas is an active member of the Toronto Area Conservators Group and also the Canadian Association for Conservation of Cultural Property as well as the American Institution for Conservation, to name a few. After many years of independent conservation, Kostas decided to take it a step further when opening his own art conservation gallery and has been successfully restoring paintings for the most notable museums in Toronto as well as the independent client ever since.
