The Government of Canada has introduced the digital services tax (DST). The DST requires foreign and domestic large businesses to pay tax on certain revenue earned from engaging with online users in Canada if they meet certain conditions. Affected businesses will have to apply to register for a DST program account and may have to file a DST return.

Appears Canada is following the EU in taxing (primarily) USA Tech companies in the near future. Politically that has resulted in an abrupt cutoff of trade/tariff negotiations. In other words, a pretty big deal. How that side of things plays out isn't a web concern for most of us, but the increasing number of nations seeking to tax digital tech worldwide is increasing, and THAT is a big deal.
One of the aspects of these nation/state revenue generation schemes is a likely reduction in BUSINESS conducted in certain geo-political areas. For the webmaster here at WW who routinely use Tech Companies (g, meta, etc) for Traffic, you might see it fall and ad revenues disappear.
View this observation of the WEB as just ONE MORE impediment for the webmaster as it is likely that these companies targeted for taxation are LIKELY to withdraw from some global areas, or find ways to mitigate their exposure. That mitigation will impact the vast majority of small business on the web, even to the point of closure.
Just one more thing to watch.
It ain't just SEO any longer!
