Since Hydro-Quebec is not an emitter as such, for established targets, my answer would be simple: the quicker and the sooner this happens, the happier we will be. The trap you must avoid is benefiting emitters at the expense of non-emitters, through various incentives, or failing to recognize the contribution of non-emitters because not as much money is at stake.
This is what I meant by my comment on ensuring that the various types of energy are treated equitably: recognizing all contributions—you mention the biomass; we can also mentioned wind energy, nuclear energy, thermal power plants—in an equitable process for all.
