Buying Copepods

[Ron99]

Does anybody know a vendor in Canada that sells live copepod cultures? Not the Tigger pods that are sold for food but some that might better thrive and reproduce in our tanks? I have a healthy population of isopods in my 75 gallon but I don't see many copepods in there. Was hoping to kick start a better population of them. I can buy some from the US but shipping is pricey so I was hoping to find them on our side of the border.
