Elder care Job in Trenton, Ontario

My husband has suffered a hemorrhagic stroke half a year ago. He is currently in a Nursing Home, but I would like to bring him home.
He needs constant care because he lacks insight into his condition, and wants to do things he can not do. He walks with a walker, but he can toilet himself. He needs someone to make sure he gets up the steps safely, and more things of that nature.
He loves to tinker with old cars, and I need someone who will accompany him to the garage (heated in winter) while he tries to work on his car to make sure he does not fall or otherwise hurt himself.
We have a large number of friends and family who drop in frequently, and we like it that way.
I am frequently away for a few hours of every day, and sometimes in the evening. Someone needs to stay with him at those times.
