VERDICT

Should I use Moneris?

Canada's largest payment processor — POS terminals, e-commerce, gateway, and merchant services - moneris.com

Depends. Choose Moneris if you're an established Canadian merchant wanting one vendor for terminals, POS, and online payments with Interac. Skip it if you're small or low-volume — monthly fees and contract complaints make Square or Stripe the better bet.
