The Candrive Research Program

Candrive (, a Canadian research program aimed at improving the safety and quality of life of older drivers, is now into its sixth year of activity. Candrive’s primary research goal is to begin a 5-year cross-Canada study of older drivers to determine the key factors that impact their driving safety. Study investigators propose to recruit 1000 older drivers, aged 70 and older, from seven Canadian cities. The study will be comparing the characteristics of older drivers with their driving performance. The results of this study will assist Candrive researchers in achieving their primary objective of determining the risk factors that are associated with older driver involvement in motor vehicle crashes. Results from this study will help with the development of an in-office decision tool to help physicians identify older drivers who may need further assessment of their driving ability. The decision tool, by identifying high risk drivers, will allow physicians to confirm the safety of the majority of older drivers.

Candrive is the brainchild of two Ottawa doctors, Dr. Shawn Marshall and Dr. Malcolm Man-Son-Hing, of the Ottawa Hospital Research Institute and the University of Ottawa, who decided eight years ago to address the many driving issues that affect seniors. Reacting to what are often unfair portrayals in the media, the doctors strongly reject age-based restrictions on driving, preferring instead to look at how the symptoms of medical conditions can affect a driver’s physical and cognitive abilities.

In 2008 Candrive was awarded a $5.5 million Canadian Institutes of Health Research (CIHR) grant to conduct the five year study of older drivers. Candrive comprises an international network of diverse researchers interested in older driver issues, including occupational therapists, physiotherapists, psychologists, kinesiologists, epidemiologists, and a number of medical specialists in geriatric medicine, physical medicine and rehabilitation, rheumatology and geriatric psychiatry.

Candrive has formed partnerships with key seniors’ groups, organizations, and governmental and non-governmental agencies to develop political, legislative and moral support for its research agenda. In addition to the long-term study, funding is also provided to conduct seven subprojects in various Canadian cities, all centred on issues related to older adults and driving, such as the psychosocial, cultural, social, and legal aspects of ensuring safety and quality of life for older drivers. Candrive has already influenced Canadian transportation policies and has the interest of other international researchers and administrators.
