Actually as I was saying earlier, the rate is currently 3.5%. With that rate of compulsory expenditures for charitable purposes, if one compares the tax savings given to the founder of the foundation with what the foundation has to give back to society, one realizes that the Canadian government takes 20 years to replenish its coffers. In any case, it's a donation. Which means the donor wants it to be for charitable purposes sooner or later.
In order to ensure that the money is spent within a reasonable timeframe by determining a rate and an obligation to spend set at 8%, we ensure that the private foundation will require 10 to 15 years to spend the money it receives for charitable purposes. The private foundation is no longer a large bank account that is sheltered from taxes for ever. By increasing the rate to 8%, the foundation is forced to truly spend money every year for charitable purposes and not hang on to the capital in the name of some great founder until the end of time.
