Canadian highways that retain the numbers of American ones across the border

I know that in Canada, there's no equivalent to the "US highway" system - the role of highway numbering is exclusively the domain of the provinces. The closest equivalents to a "national highway" would be the section of the Trans-Canada Highway through the western provinces of British Columbia, Alberta, Saskatchewan, and Manitoba, as well as the Yellowhead Route through the same four provinces -  but even with those roads, my understanding is that both roads are still technically considered a series of separate provincial highways that just so happen to have been given the same number by each province (1 and 16, respectively) for purposes of coordination.

That being said, I have noticed that some provinces do allude to US highways, in the sense that they retain the numbers of the roads that cross the border. This seems rather common in BC, especially - BC 93, BC 95, and BC 97 are all northern continuations of the US highways of the same number, while BC 99 - which I-5 connects to - is a throwback to US 99, which was decommissioned after I-5 was built.

Aside from BC, Manitoba does this some as well - US 83 becomes MB 83, and while MB 75 - the road connecting Winnipeg to the border - continues as I-29 rather that US 75, the road that US 75 becomes across the border does eventually link up to MB 75. One province over in Ontario, MN 61 - the road along the north shore of Lake Superior in Minnesota - continues on towards Thunder Bay as ON 61, and further east, in New Brunswick, NB 95 is the designation for the road continuing past the northern terminus of I-95 in Maine, eventually meeting NB 2 - the main highway of that province.

Besides what I already mentioned, what other examples might there be of Canadian provincial highways that retain the numbers of their American counterparts after crossing the border - whether they be US highways, state highways, or even interstates? I'm sure there's at least a handful of them.

The opposite happens with many Québec highways, with QC 139, 141, 147, 225, 235, 243, 253 having Vermont counterparts. Also, 1 and 16 are far from the only number given to the TCH, even though they are the most common numbers for the highway.

At one point, BC numbered all of their border-crossing highways to conform with (or get close to) their WA counterparts. WA then renumbered the highways, so the BC ones are relics of the past system.

BC 99 - I-5 (former US 99)
BC 15 - SR 543 (former PSH 1 branch)
BC 13 - SR 539 (former SSH 1B, which looks like a 13)
BC 11 - SR 9 (former SSH 1A, the first letter branch and first odd double-digit)
BC 97 - US 97
BC 41 - SR 21 (former SSH 4A)
BC 395 - US 395
BC 22 - SR 25 (former PSH 22)
BC 22A - former SR 251 (former SSH 22A)
BC 6 - SR 31 (former PSH 6)

What do PSH and SSH mean? Primary and Secondary State Highway, I would assume - right?

Pre-1975ish, Quebec used US Highway numbers for its routes - 9, 7, 5 come immediately to mind
