VIA Rail Canada had one F40PH-2 painted in an Operation Lifesaver scheme:

Unfortunately, there is no HO model...there were decals available, I don't know if they still are. I've seen custom HO models done. The real loco has recently gone in to the CAD shops near Montreal to be rebuilt, and will then sport the Renaissance paint scheme.
CN also had both a single GP40 (standard cab) loco and a caboose painted for Operation Lifesaver:

GP40:
Pacific Western Rail Systems (a Canadian Model RR shop) had a run of Atlas (?) GP40s in this CN scheme. Athearn makes an HO model of a CN caboose in op. lifesaver scheme, but it is not accurate. To get the accurate Point-St-Charles Van, you'd have to get the upcoming Overland brass model, or wait for the eventual release of the Rapido/CMT custom run of RTR plastic PSC vans. They should eventually do one in this scheme.
I know UP had an AC4400CW with OL markings, which Kato released in N scale. I don't know much about what other RRs did/do have, so I'll leave that for others.
