How to use the RESP to pay for education
You can use the money in the RESP to pay for education right away or keep it for future education. To take money out of the RESP to pay for education, the subscriber asks the RESP promoter for an EAP. The beneficiary can use the EAP money to pay for expenses like tuition, books, tools, transportation, and rent.
To receive an EAP and pay for education:
the beneficiary must enrol in full- or part-time studies at an eligible school (in Canada or abroad). Programs must meet the minimum weeks of study and hours per week to be eligible
the subscriber must request the EAP from the RESP promoter
the beneficiary must provide the RESP promoter with proof of enrolment
