For example Air Canada on the Toronto exchange is symbol 'T.AC'. Many Canadian symbols have the suffix .A or .B appended to them to designate class A or class B issues. A-Z' if the stock has more than one preferred issue. Warrants have the code '.WT' appended to the end. Rights have the code '.RT' appended to the end.
Units have the code '.UN' appended to the end.
The Wall Street Journal is one of the few papers that still list the symbol along with an abbreviated description. Its also a good place to look if you want to know if a particular stock has preferred or warrant issues. We have descriptions for most of the symbols that we can give quotes on. If you enter a valid symbol that we do not have the description for the description field will be blank. The quote will still be valid but you will need to make your own determination if it is the right symbol for the issue you seek.
