I don't believe CPP does any further checks. My ex-husband was a con artist and he was on it for his "bad back". Meanwhile he worked as a courier, and delivered things like tractor tires, doors, heavy stuff that he shouldn't have been able to lift with a bad back. He also had 5 paper routes and newspapers are heavy.

SK has a program called SAID, but you have to be level 2 and live in an approved home. I guess if you're healthy enough to live on your own you don't qualify. That just leaves SAP (Social Assistance) which gives you an extra $50/month if you are disabled. All you need for that is a doctor's note saying that you can't work. And you better be in low-cost government housing, because they give you a whopping $721 a month with the $50 added in. $671 if you're not disabled. That's for a single person.
