FWIW, that's Definitely a picture of an automatic.
I recently did my clutch master replacement & accidentally knocked the brake switch loose, so the different arrangement is obvious to me!
When installed, the switch simply sticks into the hole with a quarter turn right to "lock" it in. Bump it JUST right to twist it & it'll pop out & could then swing on it's wire to somewhere "hidden".
Canadian could be different, hopefully one of our members from "up North" will see this and comment.
Hydraulic switches HAVE been used, though I see more of them as "differential" switches to indicate failure of one side of the dual braking system (dual diagonal so a leak doesn't loose all your braking). For all I know, that type COULD be required in Canada, making for the difference from U.S. spec..
