The 10-year-old Port Lambton boy went into cardiac arrest at school at the end of March, and has been in hospital in London ever since.
The Sombra Optimist Club launched an auction on Facebook with more than 200 items up for grabs.
Organizer Elaine Kerwin, who is also a teacher at Sacred Heart, says all of the funds raised will help support Seth and his family.
“ Our thoughts would be to give half the money to Seth’s family directly, and the other half to Ronald McDonald House. That’s with the thought we would pay for the families stay, and even other families that are staying right now.”
So far more than $12,000 has been raised with more than 200 items up for bids.
The Facebook auction ends Sunday afternoon.
