Using the NIFS near infrared integral field unit behind the facility adaptive optics module, ALTAIR, on Gemini North, we have identified several massive O-type stars which are responsible for the ionization of the Galactic Ultra-Compact HII region G45.45+0.06. The sources "m'' and "n'' from the imaging study of Feldt et al. (1999) are classified among the hottest (and thus most massive) stars based on their K-band spectra. Other bright point sources show red and/or nebular spectra and one appears to have cool star features which we suggest are due to a young, low mass, pre--main sequence component. Still two other embedded sources ("k'' and "o'' from Feldt et al.) exhibit CO bandhead emission which has been taken as an accretion signature in massive young stellar objects. Finally, Nebular lines previously identified in higher excitation planetary nebulae and associated with Kr III and Se IV ions are detected in G45.45+0.06.
