15 years ago I was contributing to a RRSP matching program at my first employer for a short period of time.
I was in my mid-20s and once i quit my job, i forgot about this account, moved to a new address and lost track of it.
Few months ago Canada Life tracked me down, told me i had money sitting in it for 15 years and I could retrieve it. (It was a nice surprise)
I finally took the time to look into it today. Over 15 years, the return was 0.5%. I made $40.
