How do I create a pop up window containing a canvas?

Question

I'm creating a little paint program and I want to have a canvas pop up when I click on a button.

private void buttonNewDrawing_Click(object sender, RoutedEventArgs e)
{
    MessageBox.Show(mainCanvas);
}

Doesn't work obviously because it's asking for a string. but what can I then use instead of a MessageBox to just have the canvas mainCanvas pop up so I can use it?

Thank you in advance.
