Hey sunnyshade,
welcome to the forum! if all goes well, you could already have your COPR after 9 months of applying. If you're from a visa-exempt country, you won't be asked to submit the passport but only the photocopy of the first page, so you can travel...
If you're not visa exempt, it seems that it takes longer to process (presumably because of longer background checks) and it seems that London requests the passport at the very end, when they are ready to issue your visa. But nobody can tell you when that will be because it really depends on your own case...
For now, you are looking at 2 months for stage 1, after that if your file makes it to london and you have a straightforward case, and are visa-exempt it's reasonable to assume that you will be done 7 months later (if I follow what you said). But be aware that the stage 1 can take longer (happened at the beginning of the year ) and CIC is unpredictable.
I suppose if you are not able to submit your passport when asked for it, then as long as you let London know about it and tell them when you can submit your passport, you should be OK.
GOod luck with your application,
Sweden
