Don't hesitate to use the code ybsbt for a free CA$0.50
Easy to use! In 3 months, I've earned 100$CA and 50 just in the last 3 weeks. Paypal transfer is the best and done in 30 seconds.
Cons: you have to be active to have good paid surveys because they disappear quickly.
Also, the estimated time for surveys is rarely true and some take more than double in the end so you end up spending a lot of time for little money. Personally, I do almost nothing below $0.50/survey.
I have also noticed that some survey companies disqualify us after completing the survey, for no reason and without paying us. I won't name them but having done several, it can't be a coincidence.
