Read the scenario described below and referencing PIPEDA (e.g. Schedule I), explain which principles the complainant is alledging were breached.

A complainant is an online marketplace user. On January 10 2021, she received an email from an online marketplace ("the respondent"). The message invited her to click on a link to the online marketplace's grassroots action network's online form requesting that she "sign" a petition letter to the federal finance minister in relation to a matter of public policy relevant to the online marketplace and its customers.

The complainant objected to the respondent using her personal information to send her the email since she had never enrolled with the online marketplace's grassroots action network. She raised this concern with the online marketplace.

The complainant was not satisfied with the respondent's responses to her queries about the manner in which it purported to obtain her consent to send her the email, nor with the manner in which the respondent had handled her complaint. She thus filed the current complaint with our Office. She alleged in the first place that the online marketplace was unnecessarily retaining the personal information collected from their members who had signed the petition letter. Secondly, she alleged that when she complained to the respondent, it did not enable her to address her related concerns. Lastly, she alleged that to send the email, the respondent had, without her consent, used her email address for a purpose other than those for which they had collected it.
