Background: In Canada, 8.1 million people informally provide care without payment, primarily to family members; 6.1 million of them are employed at a full-time or part-time job. Digital technologies, such as internet-based tools, can provide informal caregivers' access to information and support. This scoping review aimed to explore the role of internet-based digital tools in reducing social isolation and addressing support needs among informal caregivers.; Methods: A systematic search for relevant peer-reviewed literature was conducted of four electronic databases, guided by Arksey and O'Malley's framework. An extensive search for relevant grey literature was also conducted.; Results: The screening process yielded twenty-three papers. The following themes were generated from the reviewed studies: searching for and receiving support; gaining a sense of social inclusion and belonging; and benefits and challenges of web-based support. The studies noted that, to connect with peers and obtain social support, informal caregivers often turn to online platforms. By engaging with peers in online communities, these caregivers reported regaining a sense of social inclusion and belonging.; Conclusions: The findings suggest that internet-based digital tools can be a cost-effective and convenient way to develop programs that help unpaid caregivers form communities, gain support, and access resources. Service providers can leverage digital tools to deliver support to caregivers within online communities.
