She said Telesat did not intend to use Relativity for the initial constellation deployment. Instead, Telesat would use the 3D printing specialist for single satellite launches to replace a satellite or add to the constellation.

Based on this, sounds like they were only planning on using Terran 1. Now that thats gone, I doubt Terran R will be used at all now that they signed with Falcon and are keeping the Blue contract open for later launches.
Or they batch up satellites for Terran R launches, as occurred with Orbcomm OG2 after the Falcon 1 cancellation in favour of Falcon 9.

Any big space project more than 3 years in the future is dubious, due to ongoing possibility of a big economic crash.
I know of no big space project that has ever met a scheduled date more than 3 years in the future, except the Apollo Moon landing. No big economic crash is needed. Space industry schedules are fantasies.  Telesat actually has a better chance than most, since they intend to use a proven LV.

I could be wrong, Counterexamples welcome.

Starlink.

Which is unlikely to be copy by anyone else. Since Starlink is build, launched and operated by SpaceX. The only entity that might be close is Blue Origin and Project Kuiper, however they hasn't build or launch anything to orbit yet.

Depends on which starting date you look at. I remember hearing Greg Wyler saying in 2015 that Elon wanted to get operational by 2019. I'm not sure I ever saw that in writing.

You know Elon time is actually a little later than projected.  Things happen that cause delays.  However Starlink is the only real operational system for high speed internet.

B. Summary of Request for Milestone Extension or Bond Porting
In this filing, Telesat requests that the Commission:

(i)
Grant extensions of (x) the first milestone in Telesat’s Grant,3 which establishes a deadline for Telesat to launch and place into operation 50% of its 117 first round satellites, from November 3, 2023, to March 19, 2028; and (y) the second milestone in Telesat’s Grant, which establishes a deadline for Telesat to launch and place into operation the remainder of its 117 first round satellites, from November 3, 2026, to June 10, 2028.4

(ii)
In the alternative, if the Commission declines to extend Telesat’s milestones, Telesat asks that its first processing round bond be ported and placed at risk against Telesat’s second processing round Modified Design system. In a contemporaneously filed amendment to its second round application (the “Companion Amendment”), Telesat is requesting that if Telesat’s milestone extension request is denied, which would have the effect of causing Telesat’s first processing round Grant to be terminated, the Commission convert Telesat’s second processing round application, which currently seeks a modification of the first round Grant, to a stand-alone second processing round application.

Wow, a 4.5 year extension request on the half-constellation deadline.  It will be interesting to see if the FCC will grant it.

I was expecting Starlink V-band to be the precedent setter.  But I forgot about Telesat.

It seems like too much of an extension, and the way it's written sounds like Telesat doesn't really expect to get it.  Just moving to the second round would probably be a good outcome for them.

Telesat and the Canadian government worked out a deal that covers about half of the expected budget for the Lightspeed constellation.

Quote
OTTAWA, CANADA – April 1, 2024 – Telesat (NASDAQ and TSX: TSAT), one of the world’s largest and most innovative satellite operators, announced that on March 28, 2024, Telesat received a letter from Canada’s Minister of Innovation, Science and Industry regarding an investment in Telesat Lightspeed. The letter states that, following several months of negotiations between Telesat and federal officials, the Government of Canada (GoC) is prepared to invest C$2.14 billion in Telesat Lightspeed by way of a loan to Telesat LEO Inc., a wholly owned subsidiary of Telesat, that is developing and will own and operate the highly advanced Telesat Lightspeed Low Earth Orbit (LEO) global broadband satellite constellation.
