The CRA sends you the Notice of Assessment after they have processed your federal income tax return. Information included on the Notice of Assessment includes:

• Refund or balance owing
• Breakdown of income
• Whether or not you are entitled to the GST/HST Credit
• RRSP deduction limit
• Repayment required for the Home Buyers' Plan
• Tuition, education and textbook carry-forward amounts
• Unused net capital losses

If any errors are discovered subsequently you'll receive a Notice of Reassessment. The CRA has three years from the date on the initial Notice of Assessment to make a reassessment. Revenu Québec sends a notice of assessment for Québec income tax.
