@edpallasounds like you got SIM jacked.. there are a few users here who reported simliar situations. It might be a good idea to reset all your passwords especially those that requires phone# to verify your identity.
What type of phone do you have? perhaps your phone is compromised in some way?
If you suspect you had fallen victim do contact your local law enforcement and the Canadian Anti Fraud Centre.
Here is a Vice story about the scam
I would suggest start documenting your online presence, prioritize your accounts that you use for banks and purchases. On a known clean computer, install a password manager (lastpass etc etc) and systematicaly reset all passwords and turn on 2FA that uses an authenticator app instead of the phone.. so even if your phone get hacked you won't get your other identities stolen.
