Scientific investigation of the question of financial exploitation of the elderly has shown the key role that can be played, in terms of detection and reporting, by professionals in daily contact with seniors: notaries, accountants, bank staff, social workers, physicians and lawyers. All these professionals can act as “probes” — as they focus on signs of wellbeing, they are also in a position to detect various forms of exploitation. This paper sets out the preliminary results from a qualitative and exploratory field survey conducted in 2014 and 2015 on a total sample of 27 “probe” professionals mainly from the Québec City region. The survey examined their willingness, and also their ability, to detect and/or report the potentially harmful situations they identify as part of their everyday work. The results can be used to analyze the resources, deficiencies and needs of the professionals concerned, and to highlight all the alternative strategies they apply to protect vulnerable clients while respecting their professional obligations.
