The issue is purely economic. Traditional Piggyback loading and unloading (ie by ramp) is less efficient than container loading (by lift). How is this difference resolved? By loading and unloading trailers by lift.…. just like a container. And once you load and unload by container, why haul the wheels and tires along, because the load can be secured better and even stacked if containers are used…Wheels and tires are always available at the destination.
And, assuming you will need an inventory of containers for transshipped goods (of which we have an awful lot in a world based economy) - having a whole separate and incompatible transport technology ie trailers is costly.
Why do some US railways still accept piggyback? Because well-paying customers insist on it. They want their goods to roll away from the terminal immediately. They won’t tolerate their goods standing still in a container stack. So they pay a premium. But the big variable is still whether the time taken to load and unload, and the fare charged, is better than the time and cost to put the trailer behind a cab and drive it all the way.
If Canadian shippers were willing to pay enough, we might see a return to piggyback.

I have heard this and I think the time to re-examine those arguments.
The sheer volume of dry van trailers (and I think you would have some limitations on lifting technologies re bulk tankers, but maybe not flatbed units) should provoke the interest of almost any organization. I believe (although I do not see recent figures) that there are over 5 million commercial trailers in the USA (no breakdown by type) (Canadian figures I found suggest 9 million trailer registrations - but I am assuming this means every non-commercial trailer as well), of which the larger majority are dry van type.
In todays day and age I have a hard time believing that better, automated lifting or transfer technologies don't exist and cannot be implemented.
Work has been done on such concepts in Poland and the EU in general, in Russia, and in China that I am aware of. Combine tofc with cofc, add in a mix of electric and hydrogen fueled motive power, add in last mile electric trucks, and you should have a much more carbon efficient method of longer distance freight movements, plus a more efficient utilization of both railways and other scarce resources i.e. drivers.
Its quite possible the 'precision rail' acts as a barrier, but I understand that a movement or some movement from precision rail to a more service orientated service may be underway in some sectors of the rail industry.
If I could source some information on the number of movements between centers i.e. Toronto-Moncton, then I think we could really have a discussion.
