George:
A few misconceptions in your post.
1. In the old days, a Res -> Reg transfer would buy back time, if elected in their first year in the Reg F, at the rank and IPC where it was earned. This has been changed; instead, old pay is inflated to modern values, modern contribution rates are charged, and then compound interest on top of this - a double hit.
2. The increase in contributions is not inflationary; in theory, 4.6% of pay will grow with inflation as the base pay increases. The increases in contribution rates are to better align employer/employee contributions, to get closer to 60%:40% (right now the employer is paying closer to 66%).
3. Under every piece of federal pension legislation existing, interest accrues at 4%, simple interest on retroactive contributions. The only group to be charged a different rate, a rate set by regulation not law, is members of the Reserve Force - they pay 7% compound interest.
4. DND/CF has failed in their implementation - it took 7 1/2 years from the law to coming into force. Or, looking at it another way, the amount it cost to buy back increased by about 60% due to the delays (vice 28% at the other interest rate)
5. The Government, in the form of a law, gave an order to DND. DND chose to ignore that order for an extended period of time (see point #2). A very bad and very dangerous precedent.
6. WIth the changes to the CFSA, a Reservist buying back pays the same rates as someone joining the Reg F. In fact, they have it worse - it costs more to buy back under the Reserve Pension Plan that under the Reg F Plan (part I.1 vs part I).
7. Despite 7 1/2 years from legislation to implementation, DND still was not (and is not) ready. Records have illegally been destroyed; others have been illegally withheld from members. In my case, a request in 2006 received a reply in 2009 - despite DND having, by law, 30 days to reply. DND has taken official requests filed in accordance with the Privacy Act, transferred them from one desk to another and announced that they are no longer official and that therefore they do not have to obey the law in meeting response times. Think about that - DND has declared itself to be above the law.
8. Staff in the pension office are overwhelmed and making many, many mistakes. In my case, it was 23 months from when I submitted my paperwork until they replied. Then they mis-counted days worked and provided incorrect data to me about the cost of the buyback; by the time they caught and corrected their error I had to take remedial action that cost me additional money to fix. They then gave incorrect information for the transfer of funds, having my bank cancel and re-issue the payment (fingers crossed, RBC hasn't come back to me for more money because of that yet). And then when working with the Canada Revenue Agency, they made errors in their filings, leading to CRA sending me incorrect data and once again forcing me to spend additional time and money to correct their errors.
In short: DND has not covered themselves in glory on this one. Ignoring legislation directing them to offer benefits to Reservists; breaking the law with respect to disclosure of pay records to members; processes unable to handle the influx of new members of the pension plan (under 30% of those eligible have eleceted to buy back, or so I've heard); charging higher interest rates... A litany of failure.
Oh, and what of those Reservists killed in Afghanistan prior to 01 March 2007? In 1999 the Government said "We want reservists to have pensions". Do you think the staff have done anything for the survivors, to get them benefits? I was nearly kicked out of an info session for asking that question - and after much prodding getting the answer "No, we're not doing anything for them."
