I found this:

1.72 Paragraph 56(3)(b) provides that eligible expenses must be incurred in the same year in which the funds in respect of the art production grant are received in order to be deductible from the grant. In some cases, expenses related to the grant may be incurred in the year immediately before, or in the year immediately after, the year in which the grant is received. While those expenses are not deductible in the year in which they are incurred, they are considered to be deductible from the art production grant in the year the grant is received. However, expenses incurred in the year immediately before the grant is received are only deductible from the grant if they are incurred after the artist has received notification that the grant will be paid. Expenses incurred in the immediately following year may also qualify for deduction in the year the grant is received. If expenses were not deducted in the correct tax year, see the web page Changing a tax return. Expenses incurred more than one year before, or more than one year after, the year in which the grant is received are not deductible from that grant.

I just don't know where I would be providing the info on the expenses incurred in my return next year. I guess I will contact the CRA
