Short answer

Opt-in consent is permission a person actively gives, such as by ticking an unchecked box, before their data is collected or they receive marketing. Laws such as GDPR and Canada's anti-spam law, CASL, generally require it. Silence, inactivity or pre-ticked boxes do not count as valid opt-in consent.
