Perhaps having extra time, Brasseur de Bourbourg began a programme of research of the history of the archdiocese of Quebec, and in particular of its 17th-century founder, François de Laval, the first Roman Catholic Bishop of Quebec (after whom the seminary's later incarnation as a University, the Université Laval, is named). The results of his archival investigations were published in early 1846 as a biography of Laval. The contents of this pamphlet seemed to displease his Canadian colleagues somewhat, for a dispute began which made his position there uncertain, or at least uncomfortable. Also, he apparently disliked the harsh winter climate (to judge by some comments he made in the dedication of his later "History of Canada"), and may also have been a factor in his departure which was soon to ensue.
