Hello, I need help getting rid of flies. I do not know what kind they are and how to get rid of them

They come from my bathroom which i have cleaned multiple time. I blocked the bath and sink drain for days and put bleach in them. I cleaned and changed the fan. They still appear from somewhere. I can kill 5-10 per days and there are 30+ stuck on the sticky paper i put on the windows which they seem to hangout? more and come from.

i come from Canada, quebec, quebec

(Sorry for bad english, it is not my first language)
