We describe an ongoing all-sky high resolution spectropolarimetric survey of all stars brighter than V=4, in support of the BRITE-Constellation space photometry mission. The observations provide a sensitive diagnosis of the stellar magnetic field with each high quality spectrum, sufficient to detect weak dynamo and fossil magnetic fields in cool and hot stars, respectively. Time allocations at CFHT and Pic du Midi observatory in 2014A have yielded over 80 stars observed, including the discovery of several magnetic objects.
