Looking for outdoor garden supplies in Vancouver, BC?

I’m making a fountain for my garden and am not sure exactly what material to use or where to find them. I want it to be three shallow dishes of different sizes that are slightly tilted, so the water pours from one to the other.

I would love some suggestions on what type of dishes I should use…I was thinking some kind of metal?

And some ideas on where I can find these dishes would be much appreciated!

Thanks so much!
