Its a good idea to always check your online trade before executing to make sure. If I remember correctly some foreign large caps Bayer, Nestle etc used to trade OTC.

[yogibearbull]

Foreign ADRs with tickers ending in "Y" Bayer/BAYRY, Nestle/NSRGY, Tencent/TCEHY, etc trade on US OTC.

Foreign tickers ending in "F" (Bayer/BAYZF, Nestle/NSRGF, Tencent/TCTZF, etc) are bought on foreign exchanges and have additional fee of $50 per transaction.

BTW, I looked at Fido and I didn't find any commissions for OTC trades. Of course, there is extra charge for foreign "F" tickers.
