A new issue of Enbridge preferred shares (Series L) started trading yesterday on the TSX under the symbol ENB.PF.U. On April 19, another issue of Enbridge preferred shares (Series J) started trading on the TSX under the symbol ENB.PR.U.
I believe there is an error in your symbology because the ENB.PR.U issue that started trading on April 19 is listed under the symbol C.ENB-US in iqfeed but with the description of Series L instead of Series J. The new issue that started trading yesterday (Series L, ENB.PF.U) is not listed in iqfeed.
