I chatted with one of their traders earlier this afternoon on a separate issue, and I asked him about Norbert's Gambit. His message to me about performing Norbert's Gambit in the RRSP was that:
1) You can still buy an interlisted stock (e.g., TD, SU, CNQ, HSE, etc.), so no need to use the DLR method and wait T+3 days, etc.
2) You can call them right away (on trade date) and not have to wait till settlement date
3) TDDI trader will perform the journal over to the US side
He indicates that the new US $ RRSP account creates more work on the part of the traders and less work on the investor. He encourages the investor to journal it over on the trade date rather than settlement to reduce the volatility (i.e., in case the initial purchase of the stock goes down). In terms of commission, he admits it's a hit or miss depending on whom you get. He says the "textbook" response is to charge the $43 or whatever phone commission. However, he himself and some other traders he knows typically do not charge the phone commission if it's a one-time journal over transaction. From what he says, it seems to be a professional judgment thing on their part. In essence, if you get a good trader, you should only be charged the initial buy and sell commission to get US cash.
