Fast Radio Bursts (FRBs) are millisecond-timescale radio transients originating from cosmological distances (~Gpc) that have been discovered a little more than a decade ago. At these distances, they have to be a trillion times more luminous than the brightest radio pulses observed from Galactic pulsars. The engine and emission mechanism that can produce such luminosities is still unknown despite ~80 different theories. Over the past few years, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) FRB backend has detected hundreds of FRBs including a dozen repeating FRBs and a few of the nearest FRB sources. The repeating nature of these FRBs, allows for precise localization with radio interferometers and a detailed study of their environment and nature with multi-wavelength observations. I will introduce the broad questions about the nature of FRBs and their promise as tools for cosmology. I will discuss recent results from the CHIME/FRB backend and the inferences that we can draw about the origins of FRBs. Apart from radio observations, I will discuss X-ray and optical studies of FRB locations and the search for prompt counterparts of FRBs. I will finish by discussing the ongoing efforts of the CHIME/FRB collaboration to build outrigger telescopes for FRB localization and indigenous plans for identifying the brightest and rarest FRBs using a ultra-wide field of view telescope.
