Has anybody ever done (or is doing) doordash deliveries by foot/public transit in downtown Toronto? If so, how much did you earn and is it viable?

I have heard from one of my friends that they knew somebody who managed to earn around $50 in around 4 hours doing doordash deliveries by foot in downtown Toronto.

I really want to earn at least some money by doing doordash deliveries, but I have no car (or even a G1 driver's license). Could I do it by foot or public transit in downtown Toronto?

Also, yes, I do know that I will probably not earn much compared to even a minimum wage job, but for now I'd be happy with at least some money while I look for a real job.
