If your portfolio lacks yield and you’re ready to do something about it, then you’ve come to the right place. I’ve scoured the real estate investment trust industry and selected three stocks with high and safe yields of 4-8%, so let’s take a quick look at each to determine which would fit best in your portfolio.

1. Dream Office Real Estate Investment Trust

Dream Office Real Estate Investment Trst (TSX:D.UN) owns 166 office properties in urban centres across Canada, which total approximately 23 million square feet of gross leasable area. It pays a monthly distribution of $0.125 per share, or $1.50 per share annually, which gives its stock a yield of about 7.6% at today’s levels.

Investors should note that Dream Office reduced its dividend by 33% in February in order to preserve its balance sheet and to bolster its liquidity position, among other factors, but I think its new rate can be sustained going forward.

2. Granite Real Estate Investment Trust

Granite Real Estate Investment Trust (TSX:GRT.UN)(NYSE:GRP) owns over 95 predominantly industrial properties in North America and Europe, which total approximately 30 million square feet. It pays a monthly distribution of $0.203 per share, or $2.44 per share annually, which gives its stock a yield of about 6.5% at today’s levels.

Investors must also note that Granite has raised its annual dividend payment for five consecutive years, and its 5.7% hike on March 2 has it on pace for 2016 to mark the sixth consecutive year with an increase.

3. Allied Properties Real Estate Investment Trust

Allied Properties Real Estate Investment (TSX:AP.UN) owns 148 predominantly Class I office properties in Canada, which total approximately 10.4 million square feet of gross leasable area. It pays a monthly distribution of $0.125 per share, or $1.50 per share annually, which gives its stock a yield of about 4.5% at today’s levels.

Investors must also note that Allied Properties has raised its annual distribution for four consecutive years, and its 2.7% hike in December 2015 has it on pace for 2016 to mark the fifth consecutive year with an increase.
