"On the contrary" vs "to the contrary "

[juliana0403]

Hello !

Is there a difference between "on the contrary" and "to the contrary"?

If so, how are those expressions different?

And could you give me some example ?

Thank You.

On the contrary intorduces a statement that says the opposite of the last one:
It must have been difficult. On the contrary it was easy.

To the contrary is when you prove the opposite:
Show me some evidence to the contrary (which proves this is wrong)
