Someone--or, given government culture, likely a whole TEAM of people toiling away deep in the bowels of the CRA--seemingly had nothing better to do than to come up with this tax scheme.  That means they--somehow--figured out what significant increase this would mean to annual government revenue.  I'd be interested to know how they determined this and how much difference it makes.

Seems a petty thing to do. However, we might be surprised.  But, we just don't know. 

So, if the new rule means an "administrative nightmare" for retailers large and small (especially small...the men and women who burn the midnight oil just getting through one month after another), then here's one solution, retailers: pay these people something more than "relatively modest wages"--and cancel all discounts.
