The GST vacation offloaded all the work to the local businesses, many who weren't ready to apply the exemption in time. Kind of a dick move to them.
It would have made more sense to give that back in the form of a tax rebate during income season, or through bonus child benefit / pension payments, etc who are usually those that needs it the most if they wanted to put it back in people's pocket faster.
Yeah, if someone can't afford a toy at $56, they're not going to be able to afford it at $53.50 even one of the most expensive exempt items I can think of, a PS5 Pro ($1075.20 after tax, not including electronic eco waste fees or whatever), only goes down by $48. Not nothing, but hardly a meaningful impact. Someone on fulltime minimum wage who spent 100% of there income on newly tax exempt stuff would save about $200 over the 2 months, but that's not even including the necessities that don't get any cheaper like rent and other bills.
