Great!  Thanks for the update. 

However, We need a capital D in De Lorimier, because it is part of De Lorimier name (a person). Rue de Florence would be with a lowercase d because Florence is a city and not a person and "de" is not part of the city name, while "De" in "De Lorimier" is part of the person name. Weird, but this is how it is specified in Odonymie Québec.
