I was born and raised in Toronto, living there for more than 50 years. I have since moved to Belleville, just down the tracks from Kingston. I would just like to say clearly that it is very, very expensive to live in Toronto compared to smaller cities to the east. Everything is more expensive, and sensory stimulation is quite huge. If it were me, I would consider moving out on my own in Kingston, then consider a move to Toronto if that is successful, taking on one thing at a time.
As for the train, it really is a beautiful sensory experience, isn't it! Why not take a trip to the big city once in a while just for fun!
I hope I didn't come across as being too bossy. It was not my intention.
