Thanks for your reply.
Indeed this is what I want to avoid. So in 2019 I had some insignificant trades, ended up having minor losses. I mistakenly reported my losses as (capital gains, in other words 50% of it was consider income, however it was actually losses) but didn't bother to fix it after assessment as it was minor and did not really change my tax return.
In 2020, my losses were actually significant and I traded often. I managed my trades myself (didn't have a broker managing my account).
I feel I should report it as self employment this year (and moving forward if any in the future).
Will I face any issue doing this? if so what would be the consequences? will CRA just change my reporting and assess it as capital losses, or there will be other issues.
I have full documentations of all of this.
Thanks
