I have completed my return and I was having troubles entering my CRA account. It said I completed the tax filling and i am done, how do i check how ill get my payment?

You will need to return to your CRA "My Account" and it will advise you in there if you are getting refund and for how much.

Usually if all goes well and you Netfiled your return and you have direct deposit- it can take in the least 8 business days to receive your refund. Please note - that this weekend is a holiday and therefore the time frame will reflect this.
