First, seniors are adults, and this type of legislation smacks of paternalism. When this type of intervention takes place, seniors are removed to emergency housing or emergency beds in LTC facilities, but it doesn't really address the problem that caused them to be in need of intervention in the first place. It depends on the type of abuse that's going on. Police should also be contacted. It varies from province to province.
Many services come and go rather quickly because of funding problems.
For short-term, emergency assistance, there is alternative housing or, where there are health care needs, beds in LTC facilities. Other people in the senior's life like neighbors, doctors, the bank manager can help keep an eye on things. Support of this kind can help build the senior's confidence to deal with the abuse. As soon as you find yourself in a caregiving situation, get information on where you can get support. Don't wait until you become overwhelmed.
