Copied from the stock-encylopedia.com: The iShares CDN Income Trust Sector Index Fund seeks to provide long-term capital growth by generally replicating the performance of the S&P/TSX Capped Income Trust Index through investments in the constituent issuers of such index. The Index is comprised of the securities of Canadian income trust issuers listed on the TSX, selected by S&P using its industrial classifications and guidelines for evaluating capitalization, liquidity and fundamentals.

The ETF is great for diversification; however, there is always a cost. This ETF has a management fee like all ETF’s and the ETF buys Income Trusts a basket of all income trusts and this includes sub par performers. I prefer to pick income trusts for my TFSA that are well suited with my investment goals.

Other than an ETF you might also consider Enervest Diversified Income Trust (EIT.UN). This fund owns a basket of high yield dividend assets and pays around a 10% annual dividend.

I did not know about LIQ.UN, I bought BR.UN that at some point went down 70% from where I bought it.

I think there is an ETF for gaming that would be worth looking into.
