The Canadain dollar is down for the fifth consecutive day as USD rises across the board on an expected Fed rate hike.Below the surface, Prime Minister Mark Carney is trying to lay the groundwork for an investment boom. He's hosting an investment summit in Canada this week and that's included a series of announcements on spending, including one on a data centre yesterday.Today's announcement is a nice carrot for companies thinking of putting money to work and mirrors what the Trump administration did in the Big, Beautiful Bill. Allowing immediate expensing on a longer-term investment gets the deductions back into corporate coffers more quickly, compounding on the time value of money.
