Do not send us sensitive documents or personal information by email. Information received this way, is too easily hacked by fraudsters, experts in identity theft.

ShareFile is our preferred method of receiving information. Submitting all required documents at the same time will help us be more efficient at processing your return. Each time documents are submitted, we go through a separate assessment process.

We understand that for some of our clients, providing GGFL with paper documents is the preferred or only solution. Our team will scan and save all documents necessary to prepare your tax return in an electronic format. Our data retention policy of 7 years meets CRA requirements. Your paper documents will be returned to you via mail after your personal tax return has been completed and delivered to you. If you have any questions, please speak with your partner.

If you receive a tax slip after your return has been filed, don’t worry. Notify us immediately to avoid penalties and interest, and we will adjust your return accordingly.

  • Please organize your tax information and only send personal tax return information; do not include your corporate or trust return information (these should be sent separately).
  • Organize similar documents together (donations, medical, T slips etc.).
  • Documents for each taxpayer should be grouped together.
  • Review documentation to ensure we do not receive duplicate information.
  • If you send us something electronically, please do not also send it by paper and vice versa.
  • If you have rental properties or self-employment income, use our Excel templates to help categorize and compile the information. DO NOT UPLOAD individual receipts. See the links below to access the appropriate template for your use.

Online form

We have developed a fillable form that will help you identify what information you need to submit. Completing and sharing this form with us is a great way for us to recognise anything that may have changed in the year as well. Click on the link below to get to our Personal Tax Organizer.

If you work or live in Quebec, you may receive an “RL / Releve” slip with your federal slip. Please provide both slips at the same time as there are deductions on the “Revele” that are not on your federal slip.

To simplify any medical claims, we recommend that you send us detailed annual statements as follows:

For medical claims covered by your insurance plan:

  • Provide the insurance claim statements for services received in 2023. Please, do not also send the individual receipts or invoices.
  • Receipt for premiums paid to a private plan.

For any medical costs not covered by an insurance plan:

  • Provide the receipt with description of service, date, name of patient and payment.


  • Request a detailed prescription summary for 2023 from your Pharmacy. If you provide a summary, do not send the individual receipts.
  • Include any travel health insurance premiums paid.
  • If a family member’s health has changed during the year, they may qualify for the disability tax credit; their doctor will be able to help with that process.
