The casino in question told me that Blacjack Surrender was a game forbidden by the bonus T&C, when it clearly wasn't. I am still in communication with the said casino (although pulling teeth is quicker and a lot more fun), so I haven't PAB'ed yet and probably shouldn't mention them by name. I used to think it was one of the more reputable ones.
This is a common trick. Most Playtech casinos forbid this game even though they claim that "Blackjack" itself is allowed. Most likely, they intended the game to be banned, but the terms were not posted correctly at the time, and they expect the PLAYER to pay for that mistake.
The most likely problems with the MG casinos are going to be with any SUB, and with the first withdrawal, (documents, ID verification, etc). It may well be worth contacting them in advance to sort this out, especially if wanting to deposit $10K per month, and play through 500K on tables.
Some may see large Blackjack bets with the SUB as one of the "indicators for bonus abuse", as they expect new players to bet more modestly, and play a variety of games while "trying the software".
As for Trident Lounge & King Neptune - perhaps not yet, it is currently in some kind of limbo, having been sold to Carmen Media, who do not seem to be sure what they are going to do with it. The website "current promotions" are STILL showing as for September 2007, although King Neptune is open for new business, but only seem to have the SUB, and perhaps a few weekend offers for regular players.
For 10K deposits, Casino Action have a 10K weekly withdrawal limit, but also offer Instant withdrawals to Neteller, not that this is now of ANY use to a CANADIAN player!
The others do not appear to have any kind of withdrawal limits, certainly none that I have managed to hit
I have withdrawn sums of 20,000 from Jackpot Factory and 15,000 from Palace Group in the past, and had no trouble getting them paid in one go.
Part of any research has to include the convenience and cost of withdrawing, this is usually not as straight forward as depositing. Canada seems a bit tricky at present, with the Neteller pull-out, and evidence that Canadian institutions are being "leant on" by the US in order to persuade them to co-operate in getting rid of online gambling (someone mentioned this might be related to plans under discussion for a united continent comprising the USA, Canada, and Mexico).
