1. For non-WTO investors, the threshold is US$4.7 million for a direct acquisition and over US$47 million for an indirect acquisition; the US$4.7 million threshold will apply however for an indirect acquisition if the asset value of the Canadian business being acquired exceeds 50% of the asset value of the global transaction.

2. Except as specified in paragraph (c) below, a threshold is calculated annually for reviewable direct acquisitions by or from WTO investors. The threshold for 2007 is US$264 million. Pursuant to Canada's international commitments, indirect acquistions by or from WTO investors are not reviewable.

3. The limits set out in paragraph (a) a apply to all investors for acquisitions of a Canadian business that:
   1. engages in the production of uranium and owns an interest in a producing uranium property in Canada;
   2. provides any financial service;
   3. provides any transportation service; or
   4. is a cultural business.

Notwithstanding the above, any investment which is usually only notifiable, including the establishment of a new Canadian business, and which falls within a specific business activity listed in Schedule IV of the Regulations Respecting Investment in Canada, may be reviewed if an Order-in-Council directing a review is made and a notice is sent to the Investor within 21 days following the receipt of a certified complete notification.
