Canada

Combined, what is the total cost of all of those programs?

Canada has 0 national security threats other than US. Entirety of budget's necessity is for poverty band aids, and prosperity enhancement which includes roads. UBI replaces all poverty/redistributive programs. There is zero cost to UBI because it is not discretionary government/empire/colony funding. Just credits and debits among tax payers. Elimination of poverty programs is genuine tax reduction.

UBI is a payment made to every eligible person, regardless of any status including wealth, every month.

Including to those who pay high taxes, their spouses and adult children, reducing their effective net tax and support rate. Because people have more money, it trickles back up to the rich, such that, as always, the rich get richer even with higher tax rates, because they still have all of the wealth.

With the numbers I ran the cost is $555,687,356,784 per year with the current population to pay for the program using the Ontario studies payment model.

Again, all UBI payment levels save money due to discretionary/mandatory budget reductions. Even ultra rich investor class gets it to incentivize them to have larger families. It makes society and ultra rich, richer. Latest $2B payment to Ukraine, could have been $600 to every Canadian. UBI encourages more UBI instead of waste/warmongering.
