The article contains no reference to the Canadian enforcement action. It is about a European enforcement action against the Canadian company in question for work it did in Europe.
Dude are you intentionally trying to be obtuse. The British data watchdog noticed that a Canadian company, AggregateIQ, was mistreating data relating to the Brexit campaign. It then talked to the Canadian data watchdog, which pursued a privacy inquiry against said company because of its mistreatment of British user data. This is one of the first examples of the sort of extrajudicial enforcement of GDPR that OP wanted to know about, Jesus.
There might of been some sort of extrajudicial enforcement of the GDPR in this case, but the second article presented only showed that intrajudicial enforcement of the GDPR occurred based on actions that took place inside the EU with respect to the data of people living in the EU.
The first article actually doesn't mention any enforcement at all in Canada, just comments by a provincial and the federal privacy commissioner. Those comments were entirely based on Canadian law, not the GDPR.
