There's room and a place where each mode fits.

I think most of us here would agree that at-grade LRT have its place on
secondary routes, where we could start building
after the primary network is completed. I don't think anyone here would argue that a line on Arbutus, Scott Road, or 152nd would warrant a full grade-separated metro system. At-grade system is suitable for those routes, but buses are also just fine for the time being, and the upgrade you mentioned can come
after we have a well-established rapid transit system (there are limited amount of fundings, after all). But for primary routes such as Fraser Hwy, and to a lesser degree King George Blvd.. Most of us just think that these are the primary regional connectors and should be built as grade-separated system.
And I'm being careful about my wording... as the word "LRT" can mean a lot of thing, ranging from completely grade-separated system (like Ottawa's), to basically just streetcars. Even the SkyTrain system we have here is being grouped into the "LRT" category in part of Asia. The issue is that some LRT advocates always seems to list the best properties of LRT, not mentioning that you cannot have all of them. For instance, people say LRT is "flexible" and "can carry about the same amount of people as heavy rail".. but the flexibility comes as a sacrifice of capacity - at-grade crossings limits the headway; closely-spaced at-grade crossing in dense neighborhood limits platform length. Another one is that LRT is "cheaper" and "can run just as fast"... but in order to improve the speed, you need more grade separations, and to grade separate, it increase cost.. and in the end, the LRT system may even cost higher than systems like SkyTrain.
Calgary is lucky (or I should say.. "have the foresight") to have a lot of right-of-way reserved for LRT when a neighborhood is developed. It also have a lot of expressways or highways with reserved RoW so the LRT can be built at-grade but with very few crossings. The problem is - they are running out of these reserved RoW - and without them, construction cost skyrocketed. Their latest line, the West LRT, was constructed 8 years ago, at a cost comparable to the Evergreen Extension today but 25% shorter in length. This is a case of grade separation driving up cost (and even that, there are still quite a few at-grade crossings on that line).
Another case is Ottawa's system - fully grade separated, but is almost 50% more expensive than Evergreen. The underground downtown section have a lot to do with the high cost, but the section outside downtown should be relatively cheap as there is already a grade-separated RoW.
Toronto build LRT as an alternative to the subway. There are dead against any elevated system, so "grade-separation" pretty much means "underground". The Eglinton Line currently under construction is expensive (but less expensive than the alternative - subway). In fact, it is the most expensive rapid transit line to be ever constructed in Canada, yet it still have a long at-grade section that limits its capacity.
LA, or pretty much every city in the US outside of NY area, are still build around private vehicles. Even with the rapidly expanding rapid transit system, I think even now most people still have the mindset of "transit = poor man's ride" [..after all these years, my relatives there still don't understand why I'm commuting with SkyTrain everyday..]. They are less interested in high-quality rapid transit system - but instead, wanting to move as many poorer people out of their car so the richer can have a less congested road to drive on. So basically, the objective is to build a big network as cheap as possible. Name one country in the world where at-grade LRT is preferred option for
primary network in major cities... I don't think there is any other than the US.
And even with that, the cost latest lines in Seattle and Portland (with some degrees of grade-separation but still have some at-grade segments) is comparable, or more expensive, than Evergreen Extension...
