searching for tickers on Canadian stocks

I see Canadian stocks are showing up in articles for companies which are primarily listed in Canada.  An example is Agnico Eagle Mines.. USsymbol is AEM.. TSX symbol is AEM as well.. it shows in the articles in the header correctly as AEM:CA, which you can add to your Portfolio.  However you cannot search the ticker data base for Canadian symbols?  Is this being worked on to allow both symbols to come up when searching for a company or ticker in the search box?  This is important for trading purposes.  Thank you.  Bea
