The SIOP 2023 annual congress in Canada is the place to meet new people and share experiences and learning.  SIOP and Canada have strong historical links ranging from past presidents, chairs of different committees and networks and a record of memorable congresses. The Canadian groups have made substantial contributions to SIOP in many topics. Also, we are in the continental home of the Children’s Oncology Group and expect to be flooded with the latest breakthroughs from their comprehensive clinical trials portfolio. In addition, SIOP’s continental North American Branch shows an impressive growth and we welcome our North American colleagues to join and become more involved in the SIOP family. The congress will be home to many international comparative debates and discussions from which we can all take home new ideas and inspiration.
