The moment you walk out of the lawyer’s office with keys in hand is one you’ll remember. It’s also the moment where a lot of first-time buyers quietly think: “Okay, now what do I actually do?”
Closing day is covered in detail elsewhere — if you want the full breakdown of what happens legally and financially on that day, read our guide to what happens on closing day when you buy a home in Niagara. But this article is about what comes right after: the first week in your new home, and the practical things worth doing before you get too deep into unpacking boxes.
This one isn’t negotiable. You have no way of knowing how many copies of your key exist — previous owners, old tenants, contractors, neighbours who house-sat five years ago. Rekeying your locks (or replacing them entirely) is a small cost with an obvious benefit. A locksmith can typically do this in an hour, and it’s money well spent on day one.

One often-missed step: set up mail forwarding at the post office if your previous address received any important correspondence. It takes five minutes online.
Before boxes take over every room, walk around the exterior of your home and make a few observations. Where does water drain? Is there anything that could become a problem heading into the next season?
