The project will start early next year for some patients in the Capital District Health Authority.
The online service will provide them with access to medical information, test results and schedules for booking checkups.
The system is called RelayHealth, a secure, online personal health-record service developed by McKesson Canada.
Company spokesman Dale Weil says the system has been in use for 13 years internationally with more than 20 million patients already online.
Health and Wellness Minister David Wilson says the system will help patients become more engaged in their care.
