I have an investment, 17 weeks, that I put on automatic reinvest.  Question, now that interest rates have gone up, when it renews will I get the higher rate and still be a 17 week  or will I get the same rate as before? 

I tried reading Section 216 guide from T.D. , but I can't say I understand it very well.  I think I can attach 216. 

It also talked about reinvesting and it might move my investment up to a longer term unit to get the same rate as before.  I don't always want going from a 2 year to a 10 year.  

Maybe I should just never use the auto renewal option.  Yes or No ?
