In fact if it has to be surrounded by an ocean then there are only two continents, Antarctica and everything else. You can cross them all without entering an ocean, only seas.
Africa being an ocean is supported by there being saltwater between it and Asia. The panama canal(s) connect freshwater lakes to bridge the gap between the Pacific and the Atlantic.
The panama canal is not an ocean…and man made. No amount of squinting could make it a reasonable argument to count it.
Then you don’t count Africa either?

If the Panama Canal doesn’t count, neither does the Suez Canal, IMO.
Technically no, not when using the same argument.
Although Australia is also surrounded by ocean so Antarctica, Australia, and everything else
