Group RESP or Not
CST and other RESP providers, such as Heritage RESP, etc. are all considered Group RESP.
CBC has a recent article on Group RESP.

Like any financial products, you will meet people who love them and you will meet others who don't.
But is Group RESP a bad idea? I think it is important to be subjective here and the answer is it really depends.
For someone to want to sign up on Group RESP, he/she must be sure that they can sustain the regular contribution or else there may be penalties. This is not always a bad thing because no one here I think would question that we all want to save for our children's education. Group RESP also means you are handing off the investment choices to the Plan administrator and typically the investments are more conservative.
Group RESP plans can be quite complex. Be sure to understand what the plan prospectus states and definitely take the time to fully understand the many fees (enrollment fees, investment management fees, trustee fees, depository charges, administration fees, etc.)
Self directed RESP plans are lower cost but just because it is lower in cost, it does not mean it is better. Of course, if you go with a self directed RESP, you take the responsibility of properly invest your contribution and the grant money.
Our family looked at this Group RESP seriously and decided NOT to go with it. We feel that the cost is a little high and we also feel that there is a lack of flexibility. The latter is a key point. We feel that we need to take care of ourselves before we can take care of our children. If for some years, our family finance is tighter, we want to have the flexibility of taking care of some immediate needs of the family and skip the RESP contribution if necessary.
While we may disagree on whether Group RESP plans like CST, Heritage RESP, etc. work better for our families, what we should agree is that we are saving for our children's education and that itselff is a good thing. We need to keep that in mind.
Like any financial decisions in life, make sure you understand what you are getting before you sign anything.
