Wilson became a leader in the abolitionist movement of St. Catharines. The following excerpts, were taken from a letter written by Wilson and published the May 6th, 1852 edition of the black abolitionist newspaper, The Voice of the Fugitive.
"I am happy to announce the formation of a Refugee Slaves Friends Society in St. Catharines which already numbers over seventy members and includes some of the most influential men in the place. Of these I would notice particularly the Honourable William Hamilton Merritt, M.P., Elias Adams, Esq., Mayor of St. Catharines, Colonel John Clark, Collector of Customs and James Lamb, Esq., Customs House officer and editor of the St. Catharines Journal."
" Colored people here are heart in hand in the cause. Three of them are on the executive committee of five, of which Mr. Lamb is chairman. The object of the society is to bear testimony against slavery by extending sympathy and friendly aid to refugees from slavery who from time to time are taking shelter in this section of Canada and by promoting the education of their children."
