This  "bond headline" and suggested ETF option  is like  telling your wife "lets go to Europe for a month's holiday !!"
And spending the whole time in Dover...and it rained for 3 weeks.
You would have done better holding JNK (NY) for 5 yrs than RQG...and made 25% in Fx on top of the 6% yield.
.
You have to accept that any low interest "safe" bonds are now probably going to sink in NAV....and have a low yield from the get go.
So ditch much of the GoC,provincials etc
Honestly a better option,safer,with better yield is rate resetting (2018/20) preferred shares.
Yes...they were a dog as rates fell....got it.
That was then...this is now.
Now they are stars....go look at some of them....up 20-35% since 1/16
Additionally,for diversity... would be something similar to  JNK....you get the yield,the bonds are already trading at a discount...go look at a 10 yr chart of it.
And an improving economy can turn the underlying pooch bond issuers into (well almost) pedigree champs...
imo
