Technology Access Centre in Bio-Innovation

Collège La Cité

Ottawa, ON


La Cité's Centre d'accès à la technologie en bio-innovation (CAT-B) contributes to the biotechnology sector by accelerating business innovation through support for process or product development and improvement. Our business model is based on a partnership with industry for applied research, co-financed by public and private funds, in which intellectual property is fully transferred to companies.

Our partners have access to qualified scientific personnel and state-of-the-art equipment. Our team has extensive expertise in microbiology, cell biology, plant biology, molecular biology and genetics. We are fortunate to be able to count on experts in the biology of cannabis, in the development of disease diagnosis tools, in precision fermentation and in cellular agriculture (cultivated meat).
