PST is dependent on region
This retail sales tax is charged when a good or service is purchased or acquired and is mandated by the provincial governments. The PST applies to both taxable and zero-rated items and is paid to the CRA.
For provinces including British Columbia, Manitoba, Quebec, and Saskatchewan, small businesses are required to charge customers the PST, as well as 5 percent GST.
