You might try Googling for Charity Knitting in Southern Ontario.
Also, Google Bev's Country Cottage. Bev has Canada listed for charity knitting and you might find Ontario listed as one of the charities. Hope you find something...so many are in need.
I belong to We Care - Maine on Ravelry (I am one of the members from Maine). Our moderator, Kathleen, does a marvelous job. We have members from many locations, not just Maine. We work on just about everything...hats, mittens, socks, baby clothes, baby blankets, etc.
