NEW YORK ( TheStreet) -- After weeks of residing in the background, Europe's debt crisis has once again taken center stage. As the futures of vulnerable euro-nations like Greece, Italy, and Ireland are being called into question, investor ire has risen and concerns have begun to mount regarding the long-term stability of the current global economic recovery.The international investing realm has become tricky to navigate as trials such as the one currently facing Europe cast a shadow over nations outside the U.S. borders. With an open eye, however, it is possible for ETF investors to target foreign nations that could hold promise in the weeks and months ahead. Canada is one example of a developed market nation that could prove stable down the road. Due to its heavy exposure to oil sands and other natural resources, I have often turned to our northern neighbor as an attractive international destination for commodities-hungry investors. Beyond its heavy exposure to commodities, however, Canada boasts other strengths as well. The nation's financial sector, for instance, has often been highlighted as being a pillar of stability not just amongst the developed nations, but across the globe as a whole. In the opening half of May, Bloomberg compiled a list of the world's strongest banks. According to their rankings, five of the institutions comprising the list's top 20 hail from Canada. According to the report, these rankings were determined using five criteria, including nonperforming assets compared with total assets; and Tier 1 capital. Over the next two weeks, investors can expect to learn more about the state of the nation's financial industry when Canada's six largest banks: Royal Bank of Canada ( RY); Toronto-Dominion ( TD); Canadian Imperial Bank of Commerce ( CM); Bank of Montreal ( BMO); National Bank of Canada; and Bank of Nova Scotia ( BNS) step up to the earnings plate. Already, forecasts for these institutions appear promising. Investors can gain access to our northern neighbor through a number of avenues. However, for now the safest option is likely the iShares MSCI Canada Index Fund ( EWC), which is designed to take a broad-based approach to tracking Canada's marketplace, capturing the largest and most liquid companies based in the nation.
