I have a colleague who showed me the application they're about to send off to Nova Scotia this weekend. It's beautifully organized, everything is clear. Documents are stapled together, carefully filed in plastic pouches, sheets with tabs separate the different sections and individuals, everything is hole-punched, and the whole thing is placed neatly in a 3-ring binder. It's a marvel of tidy organization.
However, if I may presume to speak for the people scanning applications at IRCC: DON'T DO THIS.
I've worked jobs scanning documents. Every single page from that binder will need to be fished out of its plastic pouch. Each staple will have to be picked out. The records that you so painstakingly organized will be shuffled back together hastily, hopefully in the correct order. It will take a ridiculous amount of time to disassemble and then reassemble your application, all while other applications are backing up behind yours. Having to do that to one application a day is an annoyance. Doing it 10 times a day seriously bogs you down.
The best thing to do is print everything onto standard letter- or legal-sized paper if at all possible. Paper clip the documents for each section together rather than using staples. This will ensure that your application is quick and easy to scan and index. Make it easy for the folks at IRCC - and yourself!
