Their nature currently remains elusive, despite their surprisingly high inferred number densities. This emerging population of red point-like sources is reshaping our view of the early Universe and may shed light on the formation of high-redshift supermassive black holes. Here we present a spectroscopically confirmed LRD CANUCS-LRD-z8.6 at $z_{\\rm spec}=8.6319\\pm 0.0005$ hosting an Active Galactic Nucleus (AGN), using JWST data.
