Are chriopratic expenses deductible as medical expenses also is repairs to prescribed orthotics deductible

I have an excess of chriopratic charges over my plan reimbursement level can I claim them.  Next I have had previously prescribed and paid through my plan repaired to extend the life is that repair deductible.  I was not reimbursed for those repairs.

Although the second part was answered the first question with respect to the deductibility of Chriopratic services was not entirely.  My province of residence is Ontario so is those expenses deductible in Ontario.  Thanks
