All right.
Since the question was asked in French, I will answer in French.
The Senior Safe Act came into force in the wake of an initiative by the State of Maine, the Senior$afe training program. The program came about because Maine is the state with the largest senior population in the U.S. As I understand it, the Senior Safe Act is a national law.
In Maine, the work was done in partnership with the North American Securities Administrators Association. Bank employees are trained on how to recognize the exploitation and abuse of seniors, whether by family members, international fraudsters or false advertisers. Employees are then able to report those crimes to authorities identified in the legislation, so not just anyone.
If a similar law were implemented in Canada, those types of crimes could be reported to police, as well as designated agencies who would bring the information to the attention of the public guardian and trustee. Although it is not mandatory to use the mechanism, it gives bank officers the ability to raise a red flag in an effort to put an end to the problem.
What's more, seniors are not always aware of the problem or transactions on their bank accounts. If, at the very last, they were informed and the matter was investigated, it could help stop this type of behaviour.
Most importantly, the disclosure of information is not considered a violation of privacy. Normally, bank employees are not allowed to disclose information about transactions on a customer's account.
I hope that answers your question.
