Hi, I'm on Tourist Visa but TD allowed my husband to add me on his account (full access) I just provided them with my passport and Tax Identification Number from my country. We got married March 2019 applied July and now just waiting for DM. Got "Approved in Principle" last week.
For proof of cohabitation, we included Christmas, birthday cards sent to us including the stamped envelopes. We also don't have utility bills with my name on...Don't worry too much...Love wins.
Best of luck on your application.
