As more Canadians share housing, agreeing on rent, bills, everyday spending and unexpected costs before moving in can help prevent financial disputes and strained relationships.
Sharing a home can reduce housing costs, but it also creates a financial partnership that roommates often fail to define. Royal Bank of Canada (RBC) is urging students and young adults to discuss money before moving in, rather than waiting until an unpaid bill or unexpected expense creates conflict. The bank launched a Roommate Money Guide on August 24, 2026, aimed at helping students establish clearer expectations around shared expenses. The initiative comes as shared living becomes increasingly common in Canada. RBC, citing Statistics Canada census data, says roommate households grew 54% between 2001 and 2021, while among Canadians aged 20 to 34, living with people outside a census family increased 20% between 2016 and 2021.
Start with each roommate’s own budget
Before deciding how to divide household expenses, roommates need to understand what each person can realistically afford. Income from employment, scholarships, student loans or family support should be considered alongside individual obligations such as tuition, transportation, phone bills and other recurring expenses.
That information provides a starting point for determining how much each person can reasonably contribute toward rent and shared household costs. RBC also recommends leaving room for unexpected expenses where possible.
Agree on the rules before the bills arrive
A casual promise to “figure it out later” can become difficult once expenses begin accumulating. Roommates should decide in advance which costs will be shared, how those expenses will be divided and what happens when an unplanned purchase or repair arises.
Not every expense necessarily needs to be split equally. Groceries, furniture, subscriptions and other shared purchases may be used differently by different people. The important point is that everyone understands the arrangement and agrees that it is fair.
Plan for the situations nobody wants to discuss
The more difficult conversations can be the most valuable ones. Roommates can decide ahead of time what happens if someone cannot make rent on time, needs to leave the household unexpectedly or is responsible for an expense that was not anticipated.
RBC recommends revisiting the arrangement periodically because incomes, schedules and household expenses can change during the school year. Regular check–ins can make it easier to adjust the system before a small disagreement becomes a larger dispute.
The bank has also highlighted tools including its Roommate Money Guide, a student budget calculator, NOMI Budgets and Split with Friends, which can be used to track shared purchases and repayments.
Ultimately, the issue is less about finding one perfect formula for splitting expenses and more about establishing a system that everyone understands. A short conversation before moving in can help roommates avoid the frustration that comes from unclear expectations later.
