Owner just cancelled on a three week house sit with just four days until the house sit. This is here in New Hampshire, USA. We agreed to the house sit back in mid-February, three months ago! She gave no reason except that her plans changed.
What is the policy for cancellations, especially just a few days before the house sit? Also, can I leave her a review, even though I never completed the house sit?

No, You cannot leave a review when a sit never took place.
Sorry to hear this, Pete. That truly sucks and particularly when no valid reason given. Do you have a premium membership by any chance? Unfortunately as @RedLassie says, you can’t leave a review for a sit that never took place or was cancelled before it began.
I forsee this happening more and more now with the new cancellation policy. Not good, not right.
You can’t leave a review as the sit did not take place.
The policy for cancellation is that it should be for extraordinary reasons. The reality is that they cannot force the HO to host you. You can open a dispute with THS and report this behaviour. They may or may not sanction the HO, place them on a watchlist or do nothing.
If you have premium membership you have some cancellation cover (with some requirements).
@peteswanson65 Sorry this has happened to you. Although it doesn’t help you, THS has updated its cancellation policy where both sitters and owners can cancel, selecting a reason from dropdown box.
If you have Premium membership you should be able to make a claim providing you follow all the criteria. As others have said, no review can be given for a sit that doesn’t take place.
"My travel plans have changed ". Well that covers anything and everything doesn’t it!
Just to give another perspective and no reflection on you at all. This is more for the full range of sitters who might experience similar to you.
Basically a HO might not want to get into the detailed story about their reasons, but it must be pretty significant to them to last minute cancel a 3 week trip.
@peteswanson65, really sorry to hear of your sit cancellation.
As others noted, if you are a Premium THS member then you may be eligible for Sit Cancellation Insurance. This provides up to max US$1500 (max US$150/night) for alternative accommodation that is booked within 20 miles of pet parent location. There are quirks. Recommend contact THS Member Services via phone, website chat (not AI), or email support@trustedhousesitters.com. There are quirks to eligibility and coverage - see weblink below.
If you are not Premium member then you have no coverage.
This has happened to us twice. Sucks. But life happens. Suggest take deep breath, understand THS coverage if any, and make alternative plans accordingly.
I’ve definitely noticed more HOs canceling their travel plans altogether–or deleting the dates b/c they’ve found a different solution.
I didn’t know about this. Thanks for bringing it to my attention @temba. It’s awful, particularly if people have paid for flights. What on earth was THS thinking?!
There’s a similar list of reasons that sitters can now use to cancel @Smiley.
There’s a whole thread of discussion on the whys and wherefores. I’m personally happy that sitters have an equal process to cancel. However back to the OP, we all face the possibility of disappointment in any arrangements based on Trust. 
There isn’t really any recourse. If she simply “changed her mind” you can complain to THS and ask them to watch her account which just means if this happens again AND someone complains AGAIN they might notice.
If you have the premium plan this would the time to make a claim.
If you don’t have the premium plan, this would be the time to figure out your plan B.
I did just notice an unfilled sit in NH – it might be the one you got cancelled from still up, and several “last minute/low application” sits in nearby Vermont, so I’d get busy if you still want those dates!
