I had no idea that Oshawa had a Port. It has opened for the season.
"The Port of Oshawa is Durham Region’s gateway to the world, handling more than 500 vessels carrying over 3 million metric tons of cargo over the past decade. On average the port handles $23 million worth of cargo annually, from salt and steel products to asphalt and grain. The movement of cargo through the Port of Oshawa supports 294 jobs and generates $6 million in federal and provincial taxes annually."
So I checked out Port Colborne in terms of ceremonies as it is the gateway to the Welland Canal. They had a top hat opening this week like Oshawa. The St. Niagara Independent writes:
"Per the City of Port Colborne, there are two caps involved in the annual top hat ceremony. The first hat is loaned for ceremonial purposes only from the Port Colborne Historical and Marine Museum. It’s a turn-of-the-century Tress & Co beaver felt fur hat that was anonymously donated to the museum. When not being used for the canal opening, the hat is stored in an acid-free box at the climate-controlled Captain John W. Sharpe Heritage Resource Centre. The second top hat is a keepsake for the captain of the first downward-bound vessel. It’s embroidered on the inside with a special message and the date. " |
