A fast-moving grass fire killed four people Saturday and injured dozens more. The Prime Minister has said 50 investigators are on the ground examining what happened. A U.S. food importer challenging his government's tariffs on Canadian goods in a lawsuit filed in a U.S. trade court. Geller Global said it faces a 50% tariff on cheese imports from Canada, as well as retaliatory tariffs on U.S. cheese sold in Canada.

And despite an issue with the software, the U.S. government has certified Boeing 737 Max 10 airliner for passenger service. It was introduced almost 10 years ago, but faced technical and safety-related concerns.

The glitch could prevent pilots from accessing automated flight guidance during landings. A panel of so-called safety experts didn't think it posed a safety risk. Light 92 sports, NHL yesterday.
