Supercilius Maximus might be under the influence of the "history" of the Queen's Rangers written by Stuart Bull which attempts to create a continuous line between today's Queen's York Rangers and Simcoe's rangers and Roger's Rangers.
Why today's regiment would want to be linked in anyway to Robert Rogers is beyond me. He was a liar, and embezzler,shameless self-promoter, con-man a xenophobe, cashiered from the army, tried for crimes ranging from embezzlement to cannibalism by way of statutory rape. He ended his days as a drunkard. His brother James was a far more effective commander and recruiter.
If it wasn't for Kenneth Roberts' novel I'm sure history would have forgotten him by now.
There are some quite distinct errors in S.M.'s timeline. The Highland company was the last raised. In the south. Might be some confusion there due to Allan MacNab claiming they were raised earlier and that they wore MacNab tartan kilts. He was head of the legislative council of Upper Canada in the 1830's and had delusions of grandeur which had to be bolstered by embellishing his service in the Queen's Ranger's in his youth. He actually joined quite late and was little more than a youth doing on-the-job training. If the Highland company wore tartan at all it would be Government tartan from the stores of the 71st.
There WERE rifle armed companies, as the Queen's Rangers absorbed a number of small Loyalist units from the New York area. However, they were quite small and might have been spread amongst the other companies.
The Hussar cap WAS adopted after being shot at by their own pickets in the southern campaign. By that time there was only one mounted troop, due to a lack of horseflesh.
Simcoe's rangers during his stint as Lieut. Governor of Upper Canada were not raised from loyalists in the province. They travelled with him from England and were recruited from Swiss and German troops amongst Emigre regiments. The only Loyalists there would be were amongst the officers. He brought with him 17 commissions and warrants. Most of these were granted to former officers of the AWI regiment, or their sons.
Also they did not " build " Yonge st. in Toronto all the way to lake Simcoe. Only about 5 km from Lake Ontario northward. It didn't reach lake Simcoe 'til the 1850's.
This body of troops were not known as " the Queen's Rangers", simply as "Simcoe's rangers at York". They were not a British Army unit, merely a small battalion as the Lieut. Governor's guard.
The furthest back today's Queen's York Rangers can truly trace their lineage is to Button's Troop of Militia Cavalry raised to patrol the province during the 1837 Rebellion in Upper Canada. If I were the U.S. Army I would take great offence at the QYR for using the badge of the 1st. American Regiment, Queen's Rangers from the AWI. Many of their exploits in the south bear close resemblance to the ethnic cleansing in today's Balkans!
By the way, I live in Toronto, have had close dealings with the QYR, and have spent a great deal of time over the years in the Toronto Reference Library reading and researching Simcoe's and Lady Simcoe's diaries concerning the period and the rangers.
