Might I need a credit score to rent, or for any other non-borrowing finances?
Alas, institutions do not always act rationally, and being an outlier by never having debt may be bad enough. Therein is your problem. The question, then, is do you want to do business with institutions that are not acting rationally? While I cannot specifically speak to Canadian business practices, I have to imagine that in terms of credit history as a prerequisite to a lease, it can't be too different than America. It is possible to live without a credit score. This is typically done by those with enough resources that do not need to borrow money. To make transactions that commonly use credit scores, such as a lease, they will provide personal financial statements (balance sheets, personal income statements, bank statements, pay stubs, tax returns, etc...) to show that they are credit-worthy. References from prior landlords may also be beneficial. Again, the caveat is to elect to only conduct business with those individuals and institutions that are intelligent and rational enough to be able to analyze your financial position (and ability to pay) without a credit score. Therefore, you'll probably have better luck working with individual landlords, as opposed to corporate-owned rental complexes.
