30k in rrsp & 50k in tfsa

I've never done ETF. I have pension so I don't need any cad stocks/ bonds. The goal is Max growth for the next 20-25 yrs, except in rrsp because it can't grow too much and clawback on my oas Will have another 45k cash to invest a yr from now Im thinking 100% qqc:ca for 30k in rrsp 80% qqc:ca tfsa 20% zsp (sp 500) for tfsa I'll Max out tfsa every yr Is this too aggressive for a 40 yo who'll retire in the next 20 - 20 yrs?
