What common sense do new immigrants have when they first arrive in Toronto?

In fact, with the economic globalization, I don't think I need to bring anything except money. If someone lives, I need to bring the necessary clothes according to whether the entry time is winter or summer. Generally speaking, it is colder than China. If it is a rented family, there may be no bedding and I need to bring it myself. If it is a hotel, I don't want it.
