Unlimited sick leave? If you are permanently disabled in Canada a company will keep paying your wages until you die? That sounds implausible, but even if it's true you could presumably expect some appreciation in your wages that you will not get if you can never work again.
Not 100% how it works in canada, but in Germany, you start off on the employer's program, then a combination of state and employer programs, then after some point (I think 18 months of non-work?) you get switched off the employer's program and onto the state's pension system, which carries some set of other consequences. I do believe pay decreases as well but not sure how much.
