Two Stoney Creek-area Boston Pizza restaurants closed their doors unexpectedly on the weekend of Aug. 11.

The restaurants, at 135 Upper Centennial Pkwy. and 727 Queenston Rd., had taken out an ad in the Aug. 9 Stoney Creek News print edition, promoting a buy-one-get-one-free pizza offer.

It's not clear why the restaurants closed. No explanation was posted on the doors of the Queenston Road location.

Mark Spadafora, the franchisee for both locations, described the closures as a "rebranding" in an email to a Hamilton Community News advertising sales representative.

Spadafora did not respond to an email requesting additional information.

The Stoney Creek News became aware of the closures early last week, when customers called to inquire about the Aug. 9 print ad.
