I suspected the same thing when everyone thought Ontario would boom with low oil. Much of our manufacturing is to supply O&G and mining. Hydro rates keep rising thanks to the lawyers and politicians who eviscerated Ontario Hydro to create an electrical system nightmare that cost billions. 2000 MW's of wind power that were pumping out 63 MW a couple of days ago on one of the hottest days in Ontario. IMO it is one crazy way to operate a power system. My career (now retired)was in power system operation, both transmission and hydraulic generation.
