The CRA has come out and confirmed that the TFSA increase to $10,000/year is effective immediately (before budget gets passed into Law). You can top up your limit now.
The total maximum contribution from all previous years to date is $41,000. If you have maximized every year, and have already made your $5500 contribution this year, you can now add $4500.
