Can I send additional documents to IRCC after submitting my application online?

[noelvictoria]

I've submitted my application online last April 17. After uploading my documents in each field and submitting them, I realized that some of the documents didn't have a specific field/category for me to upload it in. Can I send these documents to them separately? There was no field to upload my IELTS and school transcripts among other things.

Thanks.
