This article examines the origins of Canadian French, focusing on it morphosyntax. This approach compares written sources, both literary and non-literary, for the 19th century, to oral sources, for the middle and end of the 20th century. While it is still possible to use oral sources from the 20th century as a baseline for written sources from the end of the 19th century, this approach is more problematic for earlier centuries. The negative adverbs pas et point are examined on the basis of a corpus of old Canadian French, and it is shown that the progression of pas with respect to point was more rapid in the context of verbal negation than in the context of argument negation in France, in New France, and in Canada. During the 18th century, even though the progression of pas, as compared to point, is parallel in France and in New France, it is nevertheless the case that certain regions of France that served as sources of immigration to Canada as well as certain social groups in New France use point more frequently. The 19th century sees a progression and a uniformization of the variant pas across all social classes in Quebec. In Ontario, the variant point was conserved until a later date in its southern border region.
