New stellar streams in the MW halo have been discovered from the precision Gaia satellite astrometric and photometric data. These streams are powerful tools for discovering past accretion events that contributed to the formation of the MW, as well as powerful probes of the MW potential. Two of these streams were found to be composed of very metal-poor stars, enabling the discovery of disrupted globular clusters well below the canonical metallicity floor. In this proposal, we request GRACES high resolution spectroscopy to study the newly discovered stream, C-11. This stream appears to be composed of both high and low metallicity bright stars (G<18), and occupies a position in the MW halo where there are few other stellar systems. GRACES spectra are ideal for precision radial velocities, metallicities, and detailed chemical abundances, all necessary to model and diagnose the nature of this stream.
