Hi Kareem,
I live in Toronto, too.
I am the process of ordering a Bob Beck Type blood electrifyer, the godzilla, which has various settings. I know I won't be using it all the time. If you can wait, and don't want to buy a cheap zapper yourself, I'd gladly let you try mine, once it is here.
Asise from following a candida diet (I know it's a pain but a must!), I have quite successfully used some homeopathic remedies to deal with candida.
