As a general rule for Canadian Beatles reel tapes, both the tapes and boxes were manufactured in Canada, but slicks were often made by using US artwork. The best way to distinguish the Canadian pressings from the US issues is the color of the box: Canada always used WHITE cardboard boxes, while the USA used either BROWN or BLUE boxes.
Beatles 8 Track releases are usually found in five main series produced in Canada between 1968 and 1980: White shell with white paper labels, Transitional hybrid configurations, Black shell (AMPEX Datapack), Black shell (Lear Jet) and Black Shell (Capitol) many of which have their own "sub-variations". See the TAPES section for more details.
Cassette tapes were introduced in Canada as late as the fall of 1968 or early 1969. Cassettes could/would have been imported from the USA prior to this. There appears to be eight main series of cassette tapes produced in Canada between 1968 and 1993: Blue Spine, Black spine, Light Bue Spine, Black and Yellow, Black and Yellow SDR, Light Blue SDR, color Inlay (5 series) and Modern Apple tapes, all of which have their own "sub-variations".
