Using 3unit townhouse using as 2

I am considering purchasing a legal 3-unit townhouse (there are 3 meters for each floor). My husband & I are planning on removing the kitchen on the 3rd floor unit and use the upper 2 units for ourselves and eventually rent the bottom unit.

Do I need to change the C of O or can I still keep it as 3unit even if I take out one of the kitchen?

Any advice is helpful,
Thanks,
