I'm a US pilot and I have flown in Canada and never have gotten
them, but I'll have to admit, I've never really tried. Is it
possible to get radar services (aka flight following) for VFR flight
in Canada?

Certainly, it works the same was as in the States. If you crossed the
border VFR, you would've had to use flight following to get the
required discrete transponder code.
