The down payment that you are able to make impacts your home affordability. You are required to make the
minimum down payment when purchasing a home which is 5% in Canada. If you make a down payment of less than 20%
you will be considered a high-ratio borrower and need to take out mortgage default insurnace. This is an
additional cost that can be paid upfront upon closing or included in the cost of your mortgage.

What ratios are used to estimate mortgage affordability?
There are two primary ratios that are used by lenders as well as in the calculation above. The first is the
Gross Debt Service Ratio (GDS) with the second being the Total Debt Service Ratio (TDS). These ratios are
designed to account for how much mortgage you can afford when taking into consideratino the cost of the
mortgage, your current debt as well as household income.
The Gross Debt Service Ratio looks at monthly housing costs in comparison to your gross household income. For
the purposes of this calculation the GDS ratio is set at 35% which means that total monthly housing costs
should not exceed 35% of your gross household income.
GDS Ratio = [Mortgage payments + Home expenses] / Annual Incom
The Total Debt Service Ratio looks at your total debt in comparison to your gross household income. For the
purpose of this calculation the TDS ratio is set at 42%. This means that total debt should not exceed 42% of
your household income.
TDS Ratio = [Mortgage payments + Home expenses + other debt obligations] / Annual Income
The CMHC corporation has set the maximum GDS ratio at 39% and TDS ratio at 44%.
