I would like to add, if you have any cupboards with water pipes running through them, (under kitchen sink) leave the doors open so the heat can get to the pipes and tell who ever is looking after your home about that, so they don't close them. With the lower temperatures in the home, and the -30 -40C that the prairies can get, frozen pipes could be a problem unless you intend on shutting your water off, and draining the pipes. Insurance companies recommend shutting off the water when leaving for extended periods.
