The clock stops ticking once you retire. Her 28 probably is indexed so it will increase a little but only a few percent a year. There is probably a bridge until OAS/CPP kick in but that's not going to be a fortune and she will get it in either case until 65 (I am assuming OTPP has a bridge).But if you take it now...does the 28k/year go up to 49k/year once you hit your 85 factor?
I actually need to call OMERS and see what's the situation with my current salary and when I can retire, take my pension, and enjoy some semblance of retirement.
