I have a criminal record in violating financial law that was to be fined for about $ 2500 US but neither like detention or going to a jail.

I am in the stream of CEC and got the invitation a week ago but have a criminal record in regards to a financial crime (borrowing my personal bank account to a 3rd person).
It was convicted on Oct 2019 in Korea and it's been about a year now. It was fined for about CA$3000 and paid & resolved a couple of months ago (almost right after the final judgement).

What I am asking here is that if I am inadmissible for entering Canada with this record...

It's not possible to say for certain. You'll need to determine what your charge equates to in Canadian law to determine if you are inadmissible or not.

The fact you never went to jail doesn't really mean anything. Plenty of people are inadmissible without every having been given a jail sentence.
