1. The 50 year limit is a bit high, a 10 year limit would suffice. If <10 yrs, 80%, else 50%.
2. Feels too restrictive, unless you meant no sale to foreign buyers for 2 years. Then more power to you.
3. Fair.
4. Not good for privacy.
5. Ok, but to what end though? taxes?
6. Agreed, in fact to go further, make sure bidding is transparent.
7. Sounds a bit prejudice. Sure the money trail is one thing, and it will definitely raise flags, but if the source of that cash is legal then it shouldn't be subjected to it. eg. a poor Canadian housewife who managed to score the next lottery numbers, shouldn't be subjected to higher taxes.
8. This doesn't make any sense to me. For two reasons, (1) most high-profile gambling sites is situated outside Canada, they just wire the money in, and (2) if you're concerned about money laundering, there are already laws in place against it. Why put gambling specifically in the crosshairs?
