Were discrepancies from the 45th parallel in the US-Canadian border ratified?

I surmise that the discrepancy resulted from the inability of 18th-century land surveyors to be more precise than that. But my question is: Did later treaties ratify the details of 18th-century measurement errors? What are the specifics of those later agreements? Were they between the U.S. and Britain, or between the U.S. and Canada, or some of each? (Here I do not have in mind the agreement rectifying the mistakes in 1783 concerning the relative locations of the Lake of the Woods and the Mississippi River; that's quite a different story.)
