"There are -- and I hasten to say
not conclusive -- but there are similarities" between the Ethiopian Airlines flight profile and that of a Lion Air flight involving the same aircraft that crashed off the Indonesian coast in October, [Marc Garneau] said. Those similarities, he said, "exceed a certain threshold in our minds with respect to the possible cause of what happened in Ethiopia. This is
not conclusive, but it is something that points possibly in that direction, and at this point we feel that threshold has been crossed. The "safety notice" means none of the aircraft can fly into, out of, or over Canada, he added: "I will not hesitate to take swift action should we discover any additional safety issues."
