I downvoted your comment because I think it is mostly factual incorrect. However, I don’t want to be too hard on you as it's also a good example of how the messaging around this policy was a complete failure.

For example, renters are unable to stop using gas heating.

I would guess a large percentage, maybe even the majority of rentals have electrical heat/heat included. And while individual renters can’t choose to switch their heating source at their current homes, making natural gas more expensive has a market effect, makes rentals with alternative heating sources more desirable.

Most people cannot afford electric cars, or if they can, the infrastructure to actually charge it (house / garage).

It’s not an all or nothing, the carbon tax encourages people to drive less. Whether they choose not to travel or go by walking, biking, carpool, public transit, consumers do have choices.

Also, although it’s obvious how much carbon tax I’m paying on my own gas bills, it’s not clear to me how much food prices have gone up as a result of carbon tax on the transportation of that food.

I agree, this definitely isn’t clear, and this is another failing in messaging. At very least, projections of these numbers should have been available right from the start. Instead, hearsay was allowed to thrive with many people believing inflation was due to the Carbon Tax. Recent studies have shown the effect on prices are almost insignificant.

Regardless of whether I can afford to make those choices, I'm not even given the opportunity to choose as I rent. My landlord isn't the one who will save on utilities or save money by having an EV. You could argue I could move to a more efficient rental, but prices have gone up so much since I moved here I could save 100% of all my energy costs and I'd still end up paying more.

So I agree in that the carbon tax can't change my usage, it only makes things less affordable.
