My recent Investing in Ontario post took a look at the Royal Bank of Canada (NYSE: RY), Manulife Financial Corp. (NYSE: MFC), and Toronto-Dominion Bank (NYSE: TD); three public companies examined by the Motley Fool this past summer.

However, Ontario is more than just Canada's financial center. Its abundance of resources and location on Great Lakes have made Ontario a manufacturing powerhouse, including steel production and automobile manufacturing in southern Ontario, and mining and forestry in the north. Toronto is Canada's film and media center, as well as an important tourism destination. Niagara Falls is one of world's most popular tourist destinations. Other Ontario companies the Motley Fool liked include Research in Motion Ltd. (NASDAQ: RIMM), Nortel Networks Corp. (NYSE: NT), and IMAX Corp. (NASDAQ: IMAX).

Research in Motion (RIM), Canada's largest public company, is well know for its BlackBerry smart phones, but it also provides software development tools and produces radio-based modems used in portable devices. The consensus recommendation of analysts surveyed by Thomson Financial is to buy RIM, and has been since April. RIM met analysts' earnings per share estimate when it reported second quarter FY2008 earnings in early October, and Wall Street expects EPS of 62 cents in the third quarter, double the 31 cents actual from a year ago. RIM has a five-year EPS growth rate of 73.5%, easily beating the S&P 500 and the technology sector average. RIM's share price has been climbing since a share split in August, to reach a 52-week high of $128.36 on Tuesday; it opened today at $124.75. Also this week, RIM announced plans to sell the BlackBerry in China, and introduced Facebook for the BlackBerry as well.

Its abundance of resources and location on the Great Lakes have made Ontario an economic powerhouse. Canada's capital, Ottawa can be found there, as well as its largest city, Toronto, which is also Canada's financial hub. Seven of Ontario's eight largest companies are financial institutions, and Toronto is also the home of one of the largest stock exchanges in the world. When the Motley Fool took a look at stock investment opportunities in Ontario this past June, three of the companies they focused on were financial institutions: Royal Bank of Canada (NYSE: RY), Manulife Financial Corp. (NYSE: MFC) and Toronto-Dominion Bank (NYSE: TD). Considering the credit crunch and the weakness of the U.S. dollar, I thought it might be interesting to see how those companies are faring now.

The Royal Bank of Canada, also known as RBC Financial Group, is Canada's largest financial institution. It has 1,300 domestic locations and offices in 30 countries. In September, RBC's Gord Nixon won Canada's Outstanding CEO of the Year award for 2007. More recently, RBC announced the acquisition of a Caribbean bank, and it was one of four Canadian banks affected by restructuring at VISA. With RBC's five-year earnings per share growth rate of 26.5% (better than the S&P 500), the consensus recommendation of analysts surveyed by Thomson Financial is to buy RBC, despite missing earnings expectations for the past two quarters. RBC's share price is near an all-time high on the NYSE, closing Thursday at $57.09 on the NYSE. RBC will release its next quarterly report on November 30.
