Hi Major:
At the current rate of exchange that 84 cent Canadian price equals about 65 cents U.S. So today on the NYSE the stock went from about 65 U.S. to 88 or an increase of 23 cents. The 88 cent U.S. price should translate on Monday to about $1.14 Cdn. on the TSE if the price holds. The New York market will be closed on Monday so Toronto by itself trading might not support this new price level.
Cheers.
