It’s worth checking the email associated with your Tim Hortons rewards account after every visit to see if you get an invite to complete a survey regarding your latest purchase.
While not often, I do receive one every now and then.
The latest offer was for the opportunity to get any sized ice coffee for $1 + tax. After completing my feedback, it was added to my app among my group of weekly offers to activate.

In addition, codes can sometimes be found on the bottom of your paper receipts or on separately printed survey slips, that can be entered online at telltims.ca, for similar offers in return for your feedback.
On the completion of your survey, you are given a validation code to write down on the receipt, which you can then redeem in-store for a special offer.
In the past, I have received $1 iced coffees and $1 10-pack Timbits.
