  Using commissioning data from the first year of operation of the Canadian
Hydrogen Intensity Mapping Experiment's (CHIME) Pulsar backend system, we
conduct a systematic analysis of the Faraday Rotation Measure (RM) of the
northern hemisphere pulsars detected by CHIME. We present 55 new RMs as well as
obtain improved RM uncertainties for 25 further pulsars. CHIME's low observing
frequency and wide bandwidth between 400-800 MHz contribute to the precision of
our measurements, whereas the high cadence observation provide extremely high
signal-to-noise co-added data. Our results represent a significant increase of
the pulsar RM census, particularly regarding the northern hemisphere. These new
RMs are for sources that are located in the Galactic plane out to 10 kpc, as
well as off the plane to a scale height of ~16 kpc. This improved knowledge of
the Faraday sky will contribute to future Galactic large-scale magnetic
structure and ionosphere modelling.
