If the private sector didn't want to fund your project and the Canada Infrastructure Bank did, there must be a reason. Did the private sector charge you extremely high rates when the Bank was offering you lower ones? Do you have favourable repayment conditions compared to the conditions the private sector would have given you? What's the difference?
Otherwise, why choose the bank if there is no difference and if there are no advantages? Did you just go with the bank because it was the only one that was willing to take the risk of doing business with you, and no one else was interested because of the significant risks?
