The results of a search for main-belt comets using Canada-France-Hawaii Telescope Legacy Survey data are updated. The remaining observations in the Very Wide segment of data, taken in the g' or r' filters, are visually inspected for cometary activity. The number of main-belt objects in the original and new data sets are 11,438 and 13,802, respectively, giving a total number of 25,240. This is the largest, and least biased, search for main-belt comets to date. One object is observed to show cometary activity, and a new upper limit for strongly active main-belt comets is derived to be 40 +/- 18.
