In the discussion of a bug on Github (here and here) is was mentioned that canals were originally intended to connect cities to the ocean also if they're not next to a lake. A city like the one shown below (image taken from the github issue) would then be able to build military ships.
As this would be quite a change, I would like it to be discussed and voted on by the community:
Proposal: Cities that are not at a lake can be connected to the ocean using canals.
To clarify, forts and citadels would still count as canals only if they're next to water, so it would only be possible to connect cities that are one tile away from the ocean. Also, this would not affect coastal buildings, which are still only buildable if the city is directly at the coast.
