Here in Canada, there are "standards " for all Police departments regarding the colour, type and size of the patrol cars. The RCMP has a national car appearance standard, so a Royal Canadian Mounted Police car is exactly the same, in apperance, right across the country. After all they are our "National Police Service "
Local city departments also have to follow the standards, for car colours and car size. Lights are standard across Canada, red and blue. and all cars have to have reflective lettering on all four sides. The standard colour is white, with horizontal red yellow and blue stripes. The standard car is the Ford Crown Vic or the Chevy Malibu. Most have divider screens and dead lock rear doors.
Un- like the USA, Canada has a national Police computer system that links EVERY Police service in the country, in real time. It is the CPIC sysyem, first in service in 1980. CPIC allows a individual Constable , in his car, to send a message to any other individual officer, any where in Canada. It also gives him criminal records for the entire country, as well as driver records and stolen items, all in under a minute. Warrants, immigration deportation orders, tatoo and nick name files, missing persons nationally, and VIN numbers, all are on CPIC.
