British Columbia (short: BC) is the Westernmost province of Canada, between the Rocky Mountains and the Pacific Ocean.
The legality of hitchhiking is described in BC's Motor Vehicle Act. According to section 182 (3), "A person must not be on a roadway to solicit a ride, employment or business from an occupant of a vehicle." However, the Act defines roadways to mean "the portion of the highway that is improved, designed or ordinarily used for vehicular traffic, but does not include the shoulder, and if a highway includes 2 or more separate roadways, the term "roadway" refers to any one roadway separately and not to all of them collectively (...)", albeit there are a number of highways which entirely bar pedestrian use (see external links). While this indicates that hitchhiking should be legal when standing on the shoulder of a highway, law enforcement may not be aware of the details of this legislation.
In practice however, hitchhiking is very popular and very easy in most parts of BC. Other than where signposts expressly prohibit it, and around Vancouver, hitchhiking is perfectly fine, and you will not have any problem from the police.
