Congrats huertdiaz and SarahRuiz!!! What's the date you received your PR, so we can update it on the spreadsheet?
On the other topic, CIC also has to ensure that people don't come to Canada just to abuse the system. In most European countries, even if you get your residence permit, it doesn't guarantee you social assistance, good health care, etc. Since the volume of immigrants is huge, it's obvious they cannot take everyone like that. For example, in Finland we also have the social assistance system, but we also don't get so many immigrants so it would become an issue. I think the government of Canada should consider not giving a permanent residence right of the bat, but a temporary one for couple of years (in Finland it's 4) in the beginning. If the marriage breaks before the four years that you have to wait for the PR, your residence permit gets canceled.
