The formation of regional alliances among sub-national governments has beco
me a common feature of Europe in the part decade and a half: However, examp
les of such alliances spanning the Triad, Europe, North America and Japan,
are far less common. In a brief outward-oriented phase in the late 1980s, t
he Four Motors for Europe expanded abroad and Ontario signed a formal agree
ment with them, establishing a number of exchanges, as well as a series of
more targeted research projects with two of the Motors. The relationship be
tween Ontario and the Four Motors war somewhat unique in terms of its trans
continental reach. This paper analyses the factors which led to the establi
shment of the alliance and assesses some of the benefits achieved and probl
ems encountered in developing it. It concludes that transatlantic alliances
must surmount additional barriers of space and cultural differences to sur
vive and require a strong degree of policy and institutional continuity to
ensure the have sufficient time to mature and develop.
