Ontario says Ottawa's tax holiday will cost the province $1 billion, but it will support the GST break for consumers.

The Ontario government says it will match the federal government’s GST holiday by removing provincial sales tax (PST) from items that are not currently covered by existing provincial rebates.

The office of Finance Minister Peter Bethlenfalvy confirms it will remove the provincial sales tax on items not already covered under provincial rebate

Last week, the Trudeau government announced a series of new affordability measures over the holiday period, including a two-month 'GST holiday' on some items beginning on Dec. 14.
