Two distributors in one city, and why it decides everything else
Hydro-Jonquiere is the municipal electric utility for the Jonquiere borough and nowhere else in Saguenay. It runs a 450 km distribution network, buys about 98 percent of its power from Hydro-Quebec and generates the rest at its own 3,900 kW hydro plant on the Riviere aux Sables. Residents of Chicoutimi, La Baie and the city's other boroughs are Hydro-Quebec customers instead.
Check the name on your bill before you do anything else, because the two sides do not work the same way. A Hydro-Quebec customer enrols in the option d'autoproduction, where a licensed CMEQ electrician files the installation request and surplus banks as kilowatt hour credits. A Hydro-Jonquiere customer is dealing with a municipal utility that sets its own terms, and this page will not tell you what those terms are because we have not verified them.
If Hydro-Jonquiere bills you, ask it directly and in writing: whether a customer-owned generator may connect, what happens to electricity you export, what interconnection and metering are required, and at what cost. Do not accept an installer's assurance in place of the utility's answer, because you are the one carrying the risk if the assumption is wrong. Ask about the LogisVert grant in the same conversation, since it is a Hydro-Quebec programme.
What a Hydro-Jonquiere bill looks like
Hydro-Jonquiere's residential Tarif D mirrors Hydro-Quebec's two-tier block structure but with its own prices: a 46.154 cents per day access charge, then 6.905 cents per kilowatt hour for the first 40 kilowatt hours a day and 10.652 cents per kilowatt hour above that. Knowing the shape matters more than knowing the numbers, because it tells you what solar can and cannot do to your bill.
The access charge is the part solar does not touch. It is billed per day regardless of how much your roof generates, so a realistic expectation is a much smaller bill rather than no bill. Anyone promising to take a Jonquiere bill to zero is misreading the tariff.
The two-tier structure works in your favour on the rest. Solar removes consumption from the top of your daily usage, and the top is the part billed at the higher price. The first kilowatt hours an array displaces are the expensive ones, which is why a household that regularly runs past 40 kilowatt hours a day sees more benefit per panel than one that does not. There is no time-of-day component, so there is nothing to gain by shifting when you run appliances.
Zoning is still administered borough by borough
Saguenay was formed in 2002 from the merger of Chicoutimi, Jonquiere, La Baie and smaller municipalities, and more than two decades later the city still administers zoning through separate borough-level reglements d'urbanisme. Chicoutimi, Jonquiere and La Baie each have their own conseil d'arrondissement. The practical consequence is that rules on rooftop equipment can differ between boroughs of the same city.
So the answer a colleague got in Chicoutimi is not evidence about La Baie, and a contractor who mostly works in one borough may be confidently wrong about another. Ask your own borough two questions by address: whether a permit or certificate of authorisation is required for a rooftop installation, and whether any architectural or heritage review applies. Note the name of who answered and the date.
Those same questions double as a test of an installer. Someone who works across Saguenay should be able to tell you which borough you are in and what it asked for last time, and show you the paperwork. Someone who treats the city as one jurisdiction has not done a job here.
The housing stock, and what it means for your roof
Saguenay is a strongly single-detached market: 48 percent of dwellings are single-detached houses, so nearly half of residents control their own roof and can decide alone. The duplex share is notably high at 13.4 percent, and a duplex roof is normally shared, so both owners have to agree and the agreement has to cover fixings, penetrations, access for maintenance and who pays when the covering is replaced. Low-rise buildings are 25.8 percent of the stock, where the roof belongs to a landlord or a syndicate of co-owners, and high-rise is effectively absent at 1.6 percent, so shading from tall buildings is not a local factor.
For a house, production comes down to orientation, shade and the roof covering. An unshaded slope facing generally south produces the most; east and west slopes still produce but give up output; a north slope rarely repays the hardware. Shading costs the most because it removes production in the middle of the day, and it needs assessing across the year rather than on the afternoon of the site visit.
Check the roof covering before anything else. Panels outlast most coverings, so one within a few years of replacement should be replaced first rather than paying later to remove and reinstall the array. In a city where you may also need a borough approval, doing the work in the wrong order means going through that process twice.
Grants and financing
Hydro-Quebec's LogisVert residential solar grant pays 1,000 $ per kW of installed capacity and covers up to 40 percent of eligible project costs, typically landing around 5,000 $ to 6,000 $ on a residential system. Installations must be completed on or after June 30, 2025, and the claim is filed through the LogisVert portal within 9 months of the installation date.
If Hydro-Jonquiere rather than Hydro-Quebec bills your address, confirm eligibility with the programme in writing before you sign a contract. That is the single most valuable phone call available to a Jonquiere homeowner reading this page, because the answer changes the economics of the whole project and it is not one we can answer for you.
Federally the options have narrowed. The Canada Greener Homes Loan, interest-free up to 40,000 $, stopped accepting new applications on October 2, 2025, and only previously approved loans are still being funded. The Canada Greener Homes Affordability Program replaced it in September 2025, delivering no-cost retrofits through provincial partners for low- to median-income households, with solar PV federally eligible but each province setting its own technology list. Canada has no federal investment tax credit for residential solar.
