All transactions that are acquisitions of a Canadian business by non-Canadians must be "notified" (ICA ss. 11-12), but only those above a 5 million dollar threshold (or 50 million dollars for indirect investments, such as shares) are reviewable (ICA s. 14). If the investor is a WTO member, the threshold was 320 million in 2012. The Act empowers a
Director of Investments which is also the Deputy Minister of Industry , to produce decisions, and reports of decisions. The thresholds, for valuations above which the ICA is to be invoked, are (according to the legislation) several and hinge on whether or not the investors are part of the
World Trade Organization. While the ICA gives Investment Canada the power to restrict investment, its mandate is only to "review...significant investments...in a manner that encourages investment, economic growth and employment opportunities" unless proposed investments specifically injure national security. According to labour economist
Jim Stanford, the Mulroney government never invoked the Act to deter a foreign investment, nor did its successors, the
Chrétien and
Martin Liberal governments. Foreign investment in Canada rose significantly in the wake of the ICA, from approximately $100 billion in 1985 to over $550 billion in 2006. The ICA was invoked for the first time when in 2008 the Conservative government of
Stephen Harper blocked the sale of the space division of
MacDonald, Dettwiler & Associates, a
Vancouver-area technology company, to US-based
Alliant Techsystems. As of November 2010, the federal government had reviewed 1,637 takeovers since 1985 and rejected only one, that of MDA. On 15 November 2010, BHP-Billiton withdrew its bid, saying the conditions had proved too onerous. == Criticism ==
