RE:Mac's is a subsidiary of Alimentation Couche-Tard,That was my guess. I expect ATC|Macs lost some business and staff but overall suffered little damage or relatively less than others. A quick google search confirms this...no bad news...but challenges definitely there
In the past rent has been finalized past their due dates, so that in itself does not bother me. Becker exercising due diligence in protecting its position is also a normal reaction
Perhaps ATC is playing some hardball wanting rent reductions?? Dunno.
