My brother in law lives in Kirkland in a fairly large house, but it is built in the early '90's I believe.
It is fully electric, baseboards and hot water tank etc.
We have Hydro Quebec, not exactly cheap, but historically supposed to be cheap dam generated electricity.
Well, he has been getting billed 750$ CDN a month for the cold months.
This has been a very cold Winter, so I think your bills are "normal".
I have an old condo where the neighbors heat a lot as they are older people, so I left the heating off expecting high bills.
I turned the baseboards down to 15C, so they never came on even once.
My bedroom was always above 20C, I think it fell to 19C two or three times, but I wear polar fleece, very heavy jogging pants etc.
I only paid 21$ a month as the minimum charge to hold a Hydro Quebec account, so it is very doable.
I work all day, so I really enjoy a nice warm work day, and when I go home I let the computer heat up my office with the door shut.
So, there are ways to cut back on expenses, such as living in apartments etc.
I could never afford a wallowing shack, it isn't me, it is just the power companies have been allowed to gouge in North America, it is a new reality.
Maybe he should live in a small, brand new Condo at his age? What are his needs?
