First, the thing you may have read elsewhere: QuickBooks Self-Employed is not discontinued. It is still sold, at about $19.99 CAD per month, and its web version is branded QuickBooks Lite at $20. Intuit still runs a QuickBooks Self-Employed support channel. Nobody is forcing you off it.
People move for two reasons. Price: NorthOS is $12 CAD per month, about 40% less than QBSE. The QuickBooks Online small-business tiers above it run higher still: EasyStart at $30, Essentials at $70, Plus at $110, and Advanced at $220 (prices as of 2026, from Intuit's Canadian pricing page).
And CRA depth. Both tools cover receipts, expense sorting, GST/HST/PST, mileage, invoices, and a tax summary. NorthOS also maps every expense to its specific CRA T2125 line, tracks the GST/HST $30,000 threshold on a rolling four-quarter basis, and includes a Quick Method calculator for all 13 provinces and territories. Intuit does not advertise those three. For a full side-by-side, read our QuickBooks Self-Employed alternative for Canada comparison.
