There appears to be a lack of diversification as well as needlessly high expenses.  I believe the Fidelity MER is around 2% while the TD Income is 1.47%.  In addition, both funds are heavily concentrated in Canada (both equity and fixed income) with the TD being 92% Canada.

I would condense it all into the Mawer Balanced Fund.  Only 0.97% MER, well diversified by both asset and geography.  Add to the fact that it has performed quite well over time with a 3yr, 5yr and 10yr compound vreturns of 8.5%, 11.4% and 6.9% respectively.  

At the age of 66 he could easily have another 20 years.  With indexed pensions, he could perhaps afford to take a bit more risk with his mutual fund(s) if they are not immediately required for income.
