Provided you meet the CRA’s eligibility (

After reviewing your completed tax return in step 4, proceed by clicking Tab 5 “NETFILE”. Read the instructions and proceed to filing your return electronically.
Don’t forget, transmitting your own return does not mean that your spouse’s or dependant’s returns are automatically sent with yours as well. You must ensure that all of your family’s returns are also filed, by following the same procedures for each of them. In doing so, you should receive a confirmation number for each family member, indicating that each return has been sent and received by the government.
