I want to share my recent experience performing Norbert's gambit at BMO investorline. The transaction itself (TD) went fairly smoothly, although I ended up a few US dollars in the red. I'm not certain if that was my fault for reading the wrong numbers or if part of the comission (like the extra SEC fees) were missing from the transaction estimate. Not a big deal in any case, a few $ get converted automatically after a few days if you don't do it yourself to even things out.
The account was messed up for a few days after the settlement date, which I had read to expect. Then it cleared up and I left it alone for a while.
I checked a week later and was surprised to find that my account was again stuck with a negative balance. I found that the day after both sides of the trade cancelled each other, I was charged interest for, I suspect, the TD shares the system thought I had borrowed on the US side of the account for a few days. At 22%, it was 0.2% of the trade. I called and after a short chat was told that's an error and it would be credited.
So, bottom line, watch your account for a while after the trade is done. I found older references for this problem online so it's not new but neither does it happen all the time from what I've read around here. Feel free to add your own experiences to the thread, we don't seem to have a lot of information on the topic.
Edit: At humble_pie's suggestion, I'll add that this was inside an RRSP account.
