My calculations don’t assume anything. I literally used age statistics, the Ontario framework for the payout, and net revenue of the Federal Government to demonstrate the cost of UBI. Find me more data, I will give you better calculations.

I don’t think you understand what it means to make an assumption. Unless you have true population data (as opposed to sample data), you’re making assumptions. True population data does not exist because we don't have UBI in Canada.

You’re using the numbers from the study along with stats from past years to justify how things will look when you implement UBI. You can either assume that implementing UBI does not affect the distribution of these stats in any way, or you can assume that they change following a certain model. You do not adjust these stats in any way, therefore you assume that these stats will remain unchanged.

There is more than enough food from waste alone to feed every single person on the planet [...]

If there's more than enough for every single person, how does it make sense to say that that the cost UBI is excessive? If we take enough food to feed everyone in the country and just distribute them to each person to ensure that everyone is fed, would that work? The food is there, so we can do it. What if instead of distributing the food, we give everyone vouchers to get their daily food? Is that any different? How about we instead give them a fungible voucher (i.e. money) that they can choose to use on food or anything else? Ditto with every other need.
