This is so stupid! I made use of this a couple years ago to replace some windows and install solar panels. This resulted in more than a dozen people coming to my home over several months doing various bits of work. Presumably they were all getting paid.
This wasn't free money and I do have to pay it all back. I would not have done the project otherwise. It made sense to me that at 0% I do get a slight discount taking inflation into account, but it was a good chunk of money injected into the economy now that was paid to Canadians. And, a bunch of that is going to make it back to the government in the form of income tax.
I don't understand why they'd cancel the program other than the government caving to conservative morons who bitch about spending and don't understand economics.
