I previously said on either this or the other thread that I would not be surprised if a deal were worked out where the two were to conduct a certain number of public duties in Canada (visiting schools, hospitals, Indian reservations, getting photographed in places the tourism ministry wants to promote, etc.) and in return be designated as "protected persons" and so get police protection while in Canada. That would still leave them time to pursue business opportunities which appear to involve something to do with the fashion industry.I’ll give funny for that, but....
The reality is the people l generally associate with are more concerned about getting fleeced by the government over taxes on grain dryers, fuel, home heating, jacked up hydro bills etc. Why would on top of all that would they want to foot the bill for a couple who are worth millions that want to escape the limelight?
Regardless of whether Harry and Megan want to "step back from the public eye", they are still going to be targets for various terrorists and nutters who have an axe to grind with either Britain or Canada. They can in theory walk away from royal duties, but they can't in practice walk away from being royal targets to whatever nutter thinks that attacking them will stop the government from approving oil pipelines or has a grudge against Canadian or British foreign policy.
Realistically the Canadian government will take a massive load of blame from the Canadian public if anything happened to the couple and it turned out that security was somehow skimped on as well as being made to look very bad around the world. The UK tabloids that are busy crapping on Meghan now would be shedding tears of grief over how this wonderful flower so beloved by Britain was crushed by those evil, uncaring Canadians and they would be milking that story line for decades and spreading it around the world.
The simplest solution from Ottawa's point of view would be if Harry and Meghan were to patch things up with the rest of the Royal Family and soldier on as was expected of them. Given that this apparently isn't going to happen then some sort of formula is required which would show them providing some token of value in return for getting the same protection as they would if they were here on normal official duties. See above for one possible answer to that.
I have no direct information saying that this is what the government's intentions are, but it's certainly a plausible solution.
