A minute book kept by the bailiffs of Dunwich during the early fifteenth century provides additional information about Canon’s career to that supplied in the earlier biography.
Besides his position as clerk, Canon had other official duties. On several occasions he collected taxes, for the corporation of Dunwich as well as the King, and in July 1425 he and several leading members of the community leased out some lands once held by Augustine Illes† (a prominent burgess of the 1330s and 1340s) to John Luke*. He himself paid taxes as a resident of the parish of All Saints’ in the town, but he was evidently of very modest means. When in May 1423 the corporation imposed a tax to raise the money needed to obtain a confirmation of the town’s charter of liberties, he paid only 5d., considerably less than the 1s. 4d. that the not particularly wealthy Henry Beaumont I* was obliged to contribute. At the end of the same decade, he was included in a list of potential contributors towards building the east quay at Dunwich, but was among those who paid nothing.
The minute book also throws doubt upon the assumption that Canon sat in the Parliament of April 1414. The 18th-century antiquary, Thomas Gardner, who was somewhat prone to error, thought that he and Nicholas Barber† were Dunwich’s MPs in that assembly, but the minute book shows that the men elected were Thomas James† and Thomas Brantham*.
