CN's Assistant Vice-President of Grain, David Przednowek says they saw strong movement early in June.

"We're about a half million tonnes of processed grain products shipped in week 45, pushing 550,000 tonnes in week 46."

He points out that compared to historical levels, those are both pretty strong weeks. 

Przednowek says going forward into July, he expects to see a slowdown in grain movement as a number of the export terminals and canola processing plants start their maintenance shutdowns.
