Today's Weather Trivia

2009: The St. Lawrence Seaway officially opened its 50th anniversary shipping season about a week later than usual due to cold winter weather. Talk of the seaway started in 1909 but it was not until 1954 that the project was approved. The seaway cost $470 million USD of which Canada paid 72%. Queen Elizabeth II and US President Dwight Eisenhower attended the opening in 1959.
