The government grant that these stations are being built under required 25% of stations to have both CCS and CHAdeMO plugs, so this is very much a marriage of convivence. I'm not sure if there is going to be another round of grants, but if Tesla is working on a dual plug stall, I suspect they would much prefer to use that.
Well it would have to be a triple plug stall to meet the requirements wouldn't it? (Tesla, CCS, and CHAdeMO.)
If they could go with just Tesla and CCS I could see Tesla making it themselves. (They already, or will soon, support CCS in Europe, but I doubt they have any plans to have CHAdeMO chargers.)
I would expect that it is possible that they will put dual plug, CCS/Tesla, stalls in the US if that gets them the subsidy money that is coming available. (They've already done dual plug stalls in Europe, so they would just have to develop the V3 version of those stalls.) Of course there is the upcoming Californian requirement of having a display, and I think payment method, attached to the stall, so who knows what will happen there.

The Canadian Flo/Tesla chargers were done in two different Natural Resources Canada programs.
Most of them were done under the
Electric Vehicle and Alternative Fuel Infrastructure Deployment Initiative. This has been closed for a while.
There are
14 Tesla sites under this program. The first to be fully commissioned was
Salmon Arm, which was open for about a week now including the Flo chargers, but
Jasper and
Vernon are mentioned in this thread. Jasper was likely the reason that Tesla went this way in the first place, as this is in a national park, and the municipal government would
only allow them to install Superchargers if they
also installed CCS and CHAdeMO chargers.
This program was quite generous and allows for up to 75% of the stalls to have "proprietary" connectors, and of the "generic" stalls, there must be at least one CCS and one CHAdeMO connector (this would allow an "Electrify Canada|Electrify America" configuration with one CHAdeMO and the rest CCS, although Electrify Canada didn't seem to actually use this program)
From the program:
Electric Vehicle Fast Chargers: Any electric vehicle fast charger commercially available and certified for use in Canada. The charger must be a direct current fast charger (DCFC) rated for a minimum of 50 kW power output with at least one (1) charge connector that is CHAdeMO compliant and one (1) charge connector that is SAECombo (CCS) compliant or be a proprietary connector type.*
...
* Other proprietary connector types may represent a maximum of 75% of all charging connectors installed at the same project site. The remaining balance (25% or more) must be universal charging connectors (J1772, J1772 Combo, and CHAdeMO) of the same category (i.e. Level 2 or fast charger).
There was another program, the
Zero Emission Vehicle Infrastructure Program. This is closing today (September 8 2021).
While the exact sites were not specified, Tesla had funding for 27 electric vehicle chargers under ZP-059. This can be deduced to be three sites, each with 8 Superchargers and 1 Flo CCS/CHAdeMO charger in
Cache Creek,
Williams Lake, and
Quesnel. Note Cache Creek already had a Pre-Existing BC Hydro (light blue) Flo charger on the lot, the Tesla supplied one is the dark blue one in the right side of the photo on the link.
The exact conditions are not publicly searchable. But in these cases there were 8 Tesla Superchargers and one Flo CCS/CHAdeMO charger installed per site, so it appears that this program required one "universal" charger per site rather than a specified percentage.
In any case Tesla did what they needed to satisfy the funding requirements. Because the
Electric Vehicle and Alternative Fuel Infrastructure Deployment Initiative closed over a year ago, they likely didn't have any opportunity to modify their Superchargers directly, hence went with the
Flo turnkey system using
AddEnergie SmartDC for the generic chargers (Flo is a division of AddEnergie).
If dual-head Superchargers were available, they could have satisfied the funding with one Flo station, the remainder of the 25% with dual-head Supercharger/CCS, and 75% Supercharger only (for example, on a 16 stall site such as
Vernon, 12 stalls Supercharger only, 3 dual head Supercharger/CCS, and 1 Flo CCS/CHAdeMO charger, compared to the 12 stalls of Superchargers and 4 stalls of Flo CCS/CHAdeMO that are actually installed for this site).
What they need to do for the US funding will entirely depend on what the wording of the legislation will be.
Given that the Electrify America network is probably the biggest non-Tesla network and that they are abandoning CHAdeMO, likely the legislation will probably only require CCS. I doubt that there would be any provisions for a percentage of "proprietary only" connectors like the NRCan wording, and I doubt that Elon's idea of a Tesla connector with available adaptor would fly either, but a dual-head Supercharger/CCS would probably qualify for funding.
