In terms of GST (the Goods and Services Tax) ...everyone in Canada who sell goods and services in Canada must charge customers GST/HST unless your business qualifies as an exception.
Being a small supplier is one of these exceptions.
However, even if you do qualify as a small supplier, you may want to register for GST/HST anyhow, because if you're not a GST/HST registrant, you won't be able to claim any Input Tax Credits and get back the GST/HST you've paid out in the course of doing business.
As for PST (Provincial Sales Tax)
You have no choice.
If you live in a province that has a provincial or retail sales tax (as PST is sometimes called) and the goods or services you sell are not PST/RST exempt, you have to register for, collect and remit it.
It's not a matter of having to make a particular amount of sales or revenue before you have to register.
