In March of this year, the Province of Quebec and the Government of Canada entered into a comprehensive integrated tax coordination agreement, what we refer to as a CITCA, whereby Quebec agrees to make a number of changes to the Quebec sales tax in order to harmonize it with the goods and services tax.
