Just $25K to fix the courts? Seems quite low. Regardless, the city can handle that in their budget. If Raonic wants to help, he should start by paying Canadian taxes.
Genie Bouchard is still a resident of Canada. I suspect she'll be making a lot more annual income (prize money and sponsorship) than Raonic will ever in his life. Raonic, and rest of his team, should learn a lesson from the 20 year old Bouchard.
I'm not sure this guy has ever made a post on this forum that didn't include a reference to taxes.
