The investigators will conduct a trial to evaluate if an online training and support platform can help adults living with type 1 diabetes (T1D) in their diabetes self-management. Investigators will compare a group that has access to the Support platform through their usual medical care to a group that accesses the platform independently. The first group will be recruited through four participating clinics in the province of Quebec (Canada). The second group will be composed of adults living with T1D across Canada. Participants will have access to the platform for 12 months and will be asked to complete online questionnaires at the beginning and after 6 and 12 months, and share their glucose reader data with the research team. A subgroup of participants as well as healthcare professionals from the four clinics will be invited to participate in an individual interview aiming to understand the barriers and facilitators of integration Support in clinical care.
