Glad you got your answer on margining. Generally, pre-TSX, NOT will be allowed zero margin by Canadian brokers, apparently TD allows 25%. Margining is a major convenience for bulls . Otherwise, you are moving cash around around all the time. Margin interest is fully tax deductible. Margin debt is a loan with full recourse to you the borrower. I like the flex and the ability to hold long term real estate equity without needing as much cashout to trade stocks. Since NOT is not an example of ultra conservative investment, added leverage will suit many NOT shareholders be they day traders or long term holders.
