My memory of 93, is that the climb to Vermillion Pass from the east is long and straight, which may makes it's apparent grade more significant. Then a gentle run through the Kootenay River valley, and other grade of the ridge to the Columbia river valley. That passes the hot springs resort, goes through a narrow canyon, and then a relatively steep straight grade to 95.
On streetview I see a 11% down grade sign near the hot springs.
Crowsnest is reputedly the lowest pass across the Rockies. Grades aren't particularly noticeable in either direction - when not towing anything. The summit itself is a set of lakes. Last time I took 22 north, rather than 2. That's closer to the foothills, but no real grades.
ON GMaps, Crowsnest is 1400m, while towns on either side are 1200.
On GMaps, I like to check a route with the bike mode. It shows elevations.
