Because he was English-speaking, use the Quebec Notables (without the é).
I add categories for where a person was born, and usually where they died (unless they lived somewhere else, and happened to die in some other place, either because they were on a trip, or because they were taken to a hospital in some other town, or something like that).
If I find the same occupation for the person in at least two records (marriage, census, death, etc.), then I add a category for that.
If somebody served in the military, I try to find the unit(s) in which they served, and add categories for each.
If I find a source saying that they graduated from a particular university, college, or even high school, I add a category for that, too.
