do not know this but could it be done if an insider was buying up large amounts of stock as the 2.4 million that just traded, and the merger news might be coming. Could it be they too (tsx) want to check out the foreign company (northwest) like the US is doing for terroist activity. Could it be that they wanted to halt this stock to see if there is a merger of merit. Cheers hope i didn't cause too much confusion. PB
