Let me rephrase - there are US dealers selling them for MSRP.
And a lot more selling them well over MSRP:

Some Chevy dealers are bumping up C8 Corvette prices well beyond its MSRP, going as high as 50 percent over list

From the moment the 2020 Corvette Stingray was announced with a sub-$60,000 starting price, everyone (rightly) proclaimed it a bargain.
It was also inevitable that some dealerships would start asking significant premiums for the first models they receive. So far, There have been reports of dealers slapping the new Corvette with markups of $30,000, or 50 percent above MSRP.
The ones selling close to MSRP are high-volume Corvette dealers. My bet is that no Canadian dealer is a "high-volume" dealer when compared to any US dealership.
