romara, I see that I- Trade is a Scotia trading platform for Canadians. That would answer why you aren't seeing the OTC level 2's from your vantage point.
I live in the states, and our popular trading platforms like TD Ameritrade (what I currently use), Scottrade, etc have real time level 2 quotes for all stocks, including OTC pink sheets.
At any rate, I still find this situation strange, and will be investigating it much further.
On a separate note, I've been noticing that CANACCORD GENUITY has been very active with the movement of both AUN and AUNFF in recent days. Look to be buying AND suppressing the stock price at the same time. Anyone here know of their past or current connections with Aurcana??
