About the Ontario Tumour Bank

The OTB logo consists of a diamond shape made of nine smaller diamonds in green and grey, followed by the words ONTARIO TUMOUR BANK.

The Ontario Tumour Bank (OTB) is a biorepository of a wide variety of tumour and blood samples collected from state-of-the-art hospitals and cancer centres across Ontario: Kingston Health Sciences Centre, London Health Sciences Centre, St. Joseph’s Healthcare Hamilton, and The Ottawa Hospital.

OTB provides a viable solution for cancer researchers who often face challenges in obtaining the quality and number of biospecimens required for their studies. In doing so, OTB accelerates cancer research for the development of better patient diagnostics and therapies.

OTB provides cancer researchers with a diverse selection of high-quality biospecimens and derivatives, comprehensively annotated with de-identified clinical data. Biospecimens are the key to the development and testing of next-generation diagnostics and treatments. Since 2004, OTB has been making this type of research possible by collecting and dispensing the biospecimens needed for high-impact studies.
