I suppose their manufacturing base in Mexico is enough to cover their entry level to mid range products and the American manufacturing hubs is enough to cover the mid range to high end lines so the Canadian line became redundant. I'm not sure when exactly did fluorescent luminaire production move from Canada to Mexico for the entry level products but it was probably sometime in the 2000s.

Unfortunately this was the case with a lot of US based manufacturers with Canadian subsidiaries, 30+ years ago companies like GE, Westinghouse, Line Material, Sylvania, Philips, Cooper, Lithonia, and McGraw Edison all had Canadian subsidiaries that manufactured lighting products for the Canadian market. This included finall assembly but some manufacturers had Canadian specific castings as well. This started to decline by the 1990s and by the 2000s a lot of those subsidiaries ceased manufacturing and were just offices and warehouses that imported lights. The cost cutting of that era, and also the free trade act and later NAFTA probably made it more attractive to shut the Canadian plants down, especially when you consider the low population density of Canada making distribution expensive, Canada's population is similar to that of California but in a area much larger in size.   

  What about China? Do you know how globalization and tariffs factor into those broader trends?

Relatable! Liked them since 1!

 Wow! How did your brain do that so young? I was first inclined to fluorescents, incandescents and halogen bulbs in my house and I even broke a few fluorescent tubes in the garage on accident without my parents knowledge. The only bulb I couldn't touch was the CFL, my parents refused to let me play with that. Understandable, CFLs pose minor safety risks primarily because they contain about 3 to 5 milligrams of toxic mercury vapor and can  overheat at the end of their lifespan. What were your first favorite bulbs as a child?

I thought of street lighting in our town as a kid, as individual souls yes, most memorable ones were a pair of Stanton 7As either side of the canal bridge that I passed in my 12 years of school life, that I knew as 'the sisters' 😀, then on the same route, there was a twin arm REVO column on the roundabout that carried twin 135 watt SOX in Hyperion B lanterns, (these are the ones I miss the most in our town), as it was special for me as a kid to see such large SOX lamps in amongst all the Beta 5s 😎

The last one was an unusual installation on a corner in Sutton Lane, where there was this random, (quite out of place), 8 metre column with a 90 watt SOX on its own, surrounded by 35 watt SOX, the 90 was in between two trees, I called her the mysterious old lady as a kid! 😄

Today ALL our columns are just generic steel of all the same make and height, carrying all the same LED lanterns! 😖, I really miss our concrete ones that all had they're own unique, inanimate personalities 🙁

I definitely know how that feels! To me, the street lights with one fixture were female and the street lights with two fixtures were male. Even the modern LED street lights are no exception, I see faces in them just as much as I saw in HIDs. The Lithonia DSX Series, the Holophane HMAO Series and the AEL Autobahn Series all look like they have something to say.
