Buy Bird Spikes In Canada Does Anyone Know Where I Can Buy Bird (pigeon) Spikes?

Does anyone know where I can buy bird (pigeon) spikes? - buy bird spikes in canada

On turning a problem with pigeons on our balcony and windows, and I look forward to pigeons, to buy nails to the edge of the balcony and windows. I have a few online places that sell these notes, but if you know of shops that can be purchased? I live in Canada, but in any business ideas are always welcome. Thank you.
