to me it makes sense why these items are now being requested later. these items are date specific. if someone submitted the form/police clearance in January, it is highly likey it wouldn't be reviewed for 4-6 months (or in some cases even longer) when the file is picked up for processing. Remember, Ottawa is quick. Most visa offices take significantly longer process files. technically, a person's police clearance and personal history could change multiple times while the file waits to be picked up, so it makes sense they would want it to be the most up to date information based on the time the application is processing. Also, i believe these forms have commonly been requested during processing for various visa offices, so it could also just be a way for them to say, "well we request them again later on for a lot of files, why make someone fill it out twice."
