Disability insurance provides a monthly income replacement benefit when you are unable to work.
Some plans pay benefits even when you are still able to work. If you are unable to work the same number of hours, perform the same duties, or achieve the same productivity you can still receive a benefit to top up your income. In other words, your monthly income benefit can be based on income lost rather than your complete inability to work.

Individual disability plans can integrate with employer group plans and government income assistance plans like WCB, CPP or EI.
Businesses can also protect against the disability of their key people. Benefits can cover overhead expenses, simply provide a monthly supplement or even fund buy/sell agreements.
