The parkinglot do not belong to Walmart. We spent the night there and no issues.
Quiet, open space. Treed islands. Beauty shop, pedicure and manicure, Mickey D's, lube/tires, and other shops in Walmart. Tim Hortons nearby and more places in Walmart plaza.
Lot says it's privately owned and will be towed if not a customer but we stayed with no issues. Other trucks and rvs there also. Well lit and level lot. Store is open 7am - 11pm.
