GreatCanadianRebates.ca is the oldest and probably the best cash back website in Canada. I've earned a few hundred dollar in cash back from GCR alone, and I always check GCR first for all my Canadian online purchases.
GCR has an awesome promotion on many Scotiabank credit cards right now. When you sign up for those credit cards through GCR before May 31, you’ll get a $45 - $70 cash back once approved. From my point of view, $45 bonus for a no-fee credit card is pretty good.
If you want to sign up for GCR, please use my referral link as follows: https://www.greatcanadianrebates.ca/Register/126795/ , and GCR will give you extra $2.5 bonus (I will also get some bonus. Thanks).
