Wanted: Water kefir grains in Toronto

Hi all, I normally post in the kombucha group, I am new to this one. I am planning to add water kefir to my daily probiotic intakle. I would prefer to pick up a starter, don't want it mailed in the middle of the summer. I live in Toronto; I already contacted several people in the neighborhood about this, but the only person who answered me has milk kefir. I am wondering if someone on this site can help?
Thank you,
Do
