Name mix-up in passport vs marriage certificate.

[Thinkin]

I have got ITA to apply for Canada. Just noticed a discrepancy in the way my name shows up in the Marriage Certificate vs Passport. Using example to illustrate my issue. Suppose in my passport my name appears as:
Given Name: JOHN SMITH
Surname: (empty)

In my marriage Certificate my name appears as:
First Name: JOHN
Last Name: SMITH

Both documents have same date of birth. Spouse name in marriage certificate matches with name in spouse's passport. Will there be any issue if I submit my marriage certificate as it is? Thank you.

I don't think it's an issue. Explain the situation in LOE.
