I am in Saskatchewan and took 2 months off to attend schooling. I received a T2202 for the expense and the 2 months I attended school and received EI. Initially when I entered this - I was receiving a tax refund of an extra $1900. Next time I signed in, there was no credit for the 2 months I attended school - only the cost of the course that was taken and my refund was only $100 extra for the course costs. Should there be a credit for the 2 months I was attending school?
