I'd rather call it for Bold.

The Font is Twentieth century STD Medium.

This is Toronto Subway font.

Sorry, my bad. This is Futura.

Don't exactly have an answer but you can use Gotham or Precious Sans to achieve similar results. Helvetica always works as well, unless you want the same R as above. One thing's for sure- the font above is a paid one provided the design and the beautiful kern.
