Thank you for the question.
From a broad lens, it's available to most workers below a certain income threshold. If you are a single individual, unmarried, with no children, you could be making in most provinces up to $33,000, or have income of up to $33,000 I should say. If you're a couple or a single parent, for example—so a multi-person household—it's up to at least $43,000. That limit could be higher if you're a dual-earner couple. There is some variation in Quebec, Nunavut and Alberta, which have entered agreements to adjust the parameters.
The general story is that you're making at least $3,000 from work, and you're earning less than about $33,000 for a single individual and $43,000 for a family.
In terms of the advance payment proposal that was in the 2022 fall economic statement, it would essentially say that if you received the Canada workers benefit in a particular year—let's say 2022—based on your work and your income in 2022, we're going to automatically provide half of the amount of your entitlement as an advance payment during the subsequent year. That would be starting in July, and then October, and then January. If you're eligible for more when your tax return for the next year is assessed, you would get the remainder at that point.
