This is a storm that's been brewing for the entire 30 years i've been an engineering graduate.
The Tech sector, by and large, has never registered with the provincial engineering associations. Electrical, Mechanical, Chemical, Software, etc., I've worked for a string of companies that are full of engineering graduates, all who were hired to work as some kind of Engineer and are doing so and it says so on their business cards. NONE of them claim to be *Professional* Engineers, which until a few years ago was the only protected term (at least, here in BC).
EGBC (Formerly APEGBC) tried many, many ways to get these "scofflaws" to join up, with various campaigns, but never managed to convince people to give them $500/year for a magazine subscription that was mostly about Civil engineers. They managed to finally convince the government to change the Engineers and Geoscientists act to replace "Professional Engineer" with "Engineer" as the protected term. They also brought in Firm registration, whereby companies employing Engineers need to register as Engineering Firms and pay their own registration fees.
By forcing companies to register, and making registration contingent on all of the employed engineers being registered, that shifts the burden of recruitment to the firms themselves... If the company wants to maintain their registration then they have to ensure employees are registered.
How this will all play out in the long term has yet to be seen. COVID killed a lot of momentum in this area, but now that we're coming out the backside I expect a lot of firms are going to be getting letters from the association saying they need to join up and bring their employees with them.
