Here is an answer from TSX Yesterday:
Important Notice to Web Site Visitors:
We are currently experiencing a problem with the display of incorrect volumes for Canadian securities. We are working with our web content vendor to correct this issue as soon as possible and apologize for any inconvenience.
I posted this on another forum:
recently this had happened with the price of gold reported by the TSX as $ 1168.00/oz.
As a little joke, I sent them a message offering to sell below bid price, but received a dry answer: the TSX does not buy or sell. LoL.
