I don't pretend to know much about tanks, but as the old saying goes, I know one when I see one.
I also know that Canada has purchased 100 Leopard tanks from Europe, mainly from the Dutch. Therefore when I saw this tank with "NL" on its side, I assumed that this is one of them.
More info here:
It arrived by ship without the tarp, but that was added before it was loaded aboard this Paron trailer hauled by one of Mills's big Western Stars.
