What's it called when you explore old, abandoned homes/buildings?

No, there is no law saying how long you can live in any province. You can come and go as you wish. You'd want to insure your vehicles in Newfoundland, but check what your insurer says about time spent out of province.

You may also want to tell your house insurers that the house in Ontario will not have someone living in it full time, in which case they will probably raise your premium. Many of them have stipulations about leaving a house unoccupied for any length of time and, particularly in winter, they want to have someone check on it every so often. Don't tell them, and if something happens they might not cover you.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
