In 1837 Mr. Richardson was stationed at Toronto. The following year he travelled as a general missionary. The British and Foreign Bible Society having established a branch in Canada, Mr. Richardson was, in 1840, appointed its agent, he having received permission of the Conference to act in that capacity. This office he filled, with advantage to the Society and credit to himself, for eleven years. While acting in that capacity he often filled Wesleyan pulpits, preserved the most cordial relations with his old friends belonging to that Body. In 1842 he became Vice-President, and in 1851 President, of the Upper Canada Religious Tract and Book Society. He retained the latter position to the time of his death. In 1852 he was again appointed Presiding Elder of his Church. After occupying that position for two years his health was so much impaired that he was granted a superannuation, which he held for four years. On the 29th of March, 1858, he sustained a serious bereavement in the loss of his wife. At the Conference held in that year he reported himself able to resume his labours, and was once more appointed to the charge of a district, but before the close of the session he was elected to the Episcopal office. He was consecrated by Bishop Smith, on Sunday, the 22nd of August. He forthwith entered upon his duties. During the next two years he was in an infirm state of health, but a brief respite from work restored him, and he resumed his Episcopal and other duties with even more than his wonted vigour. In 1865 he visited England on behalf of Albert College, Belleville. The College Board was hampered by a heavy debt, and it was found impossible to relieve the pressure by Canadian subscriptions alone. Bishop Richardson accordingly, at the request of the College authorities, crossed the Atlantic to solicit aid there. He was accompanied by his daughter, Mrs. Brett, wife of Mr. R. H. Brett, banker, of Toronto. They were absent about six months, during which they visited many of the principal cities and towns of England and Scotland. The Bishop was indefatigable in his exertions, but the Reformed Methodist Church in England is not a wealthy Body, and it had enough to do to support its institutions at home. For these reasons the subscriptions obtained were neither so large nor so numerous as had been hoped, though the expedition was by no means a fruitless one.
