The Green Bank North Celestial Cap survey is one of the largest and mostsensitive searches for pulsars and transient radio objects. Observations forthe survey have finished; priorities have shifted toward long-term monitoringof its discoveries. In this study, we have developed a pipeline to handle largedatasets of archival observations and connect them to recent, high-cadenceobservations taken using the Canadian Hydrogen Intensity Mapping Experiment(CHIME) telescope. This pipeline handles data for 128 pulsars and has producedmeasurements of spin, positional, and orbital parameters that connect data overobservation gaps as large as 2000 days. We have also measured glitches in thetiming residuals for five of the pulsars included and proper motion for 19sources (13 new). We include updates to orbital parameters for 19 pulsars,including 9 previously unpublished binaries. For two of these binaries, weprovide updated measurements of post-Keplerian binary parameters, which resultin much more precise estimates of the total masses of both systems. For PSRJ0509+3801, the much improved measurement of the Einstein delay yields muchimproved mass measurements for the pulsar and its companion, 1.399(6)\Msun and1.412(6)\Msun, respectively. For this system, we have also obtained ameasurement of the orbital decay due to the emission of gravitational waves:$\dot{P}_{\rm B} = -1.37(7)\times10^{-12}$, which is in agreement with the ratepredicted by general relativity for these masses.
