Actually, if you look at standard e12-07 from Hydro-Quebec, you will find it is feasible to feed electricity back to the grid. I know there is some red tape, but the last government made it mandatory for Hydro-Quebec to accept people to feed back into their system.
You need a UL1741 or CSA C22.2 No 107.1-01 Inverter + power source.
An important fact is that you will never receive a check in the mail. You can only reduce your bill. Also, you cannot pay the "montly connection fee" with the energy you could be overproducing.
Also, if I remember correctly, you have 24 months to use the energy you overproduced. So, you could over-produce in the summer and use it in the winter. This would not affect you bill. It would be like using Hydro-Quebec as a big battery!
