Canadian context, clearly stated
English is the language of these tools, not a change in jurisdiction. Québec salary estimates retain Québec deductions. GST/QST uses Québec sales-tax rules. Mileage references identify the applicable year and region. Tools do not calculate US taxes or convert CAD to another currency.
Check each tool’s assumptions before using an estimate. Read the sources and limitations.
