Yes, I am worried james 
Kidding aside, in terms of diversification I believe you can own the top sector holdings across our Canadian market and avoid using the Canadian index as part of your portfolio. I just wrote about this actually since I've been thinking about this stuff of late....

Then, after you own your "top-stocks" you supplement the Canadian portfolio using VTI and VXUS in your RRSP.
No bonds here but that's because I have a small pension and I consider that a big bond. So, my asset allocation is 100% stocks.
