Final answer:
Toronto was designated its current name in March 1834 when it was incorporated, changing its name from York. There is no mentioning of Toronto being renamed after this date.
Step-by-step explanation:
The new name, Toronto, comes from the Indigenous word 'tkaronto' meaning 'place where trees stand in the water.' This name change was significant in shaping the identity and history of the city. It should be noted that prior to being named Toronto, the settlement was known as York. Toronto was officially designated as its current name in March 1834, when the city was incorporated and the name changed from York to Toronto. The other reference in the documents provided, to New Amsterdam being renamed to New York, is an example of a city that was renamed after being captured by the British from the Dutch in 1664, and the name was changed to honor the Duke of York.
