The Canadian Vision i-Tech show, which was scheduled to be held in Toronto next November, will instead be held in Calgary next March 13. The show will be followed by a new-look Vision Canada fair on Sept. 10-12, 2004 in a larger hall in the Metro Toronto Convention Centre. SILMO, which has a partnership with Vision Canada, says the increasing demand for booth space by European and other foreign exhibitors. The SILMO fair in Paris is, for its part, booked out again with 33,500 square meters of exhibition space rented out for its upcoming Oct. 17-20 session.
