I didn't find the exact quote I read previously, but I did find this:
•The family class is aimed at faster processing of spouse or common‑law partner applications from applicants outside Canada.
Processing times for spouses or common‑law partners in Canada are generally longer.
This is from the Inland Sponsorship guide: http://www.cic.gc.ca/english/information/applications/guides/5289ETOC.asp
Basically, CIC is telling you ahead of time, Outland applications get priority. I'm not going to argue the pros or cons of that (except getting people who can't get a visitor's visa into Canada reunited with their spouse is a good thing). I'm not looking for a debate or argument, just passing on what I have learned.
It's hard to be apart from your spouse - and I was apart from mine for 8 months, including time he was seriously injured in an accident (I didn't have a passport yet). However, you have the rest of your lives. Lets all be grateful we can be in a country where we have a Charter of Rights and we're allowed to sponsor spouses (or be sponsored). Reading some of the international news, I am more and more grateful to have the opportunity to live in Canada each day!
