French have been threatening to tear up the treaty for years. Old news.

This from back in May.

This is French posturing again. We already pay £80 million and coughed up another £20 milllion for additional fencing. Since most of these migrants have presumably ditched their passports/identity documents they won't be able to buy tickets and board boats to the UK since it's simply enough to require this online or at the booking office at the port. The infrastructure is already in place so France can't say it's going to cost more to set up.

Plus I assume once we leave the EU we are not bound by the Dublin Agreement while France still is so if they want to send the migrants elsewhere it would be back to Italy or Greece or wherever they first entered the Schengen Area.
