269,884 Electors Set for Three Federal By-Elections in 2026

Canada Gazette releases official preliminary voter counts for Terrebonne, Scarborough Southwest and University—Rosedale by-elections under the Canada Elections Act.

In the silent machinery of Canadian democracy, the Canada Gazette has just published the exact size of the battlefield for three federal by-elections. On March 13, 2026, an EXTRA edition (Vol. 160, No. 3) revealed the preliminary lists of electors: 91,052 names in Terrebonne, Quebec; 85,433 in Scarborough Southwest, Ontario; and 93,399 in University—Rosedale, Ontario. The combined total of 269,884 electors now stands as the official measure of the contests that will fill vacant seats in the House of Commons.

Precise Elector Counts Published for Pending Federal By-Elections

The determination was signed March 11, 2026, by Chief Electoral Officer Stéphane Perrault. It appears pursuant to subsection 93(3) of the Canada Elections Act and is printed side-by-side in English and French for immediate nationwide access. The bilingual publication lists them plainly:

• Terrebonne, Quebec: 91,052 electors

• Scarborough Southwest, Ontario: 85,433 electors

• University—Rosedale, Ontario: 93,399 electors

These figures mark the legal starting line. From this moment, returning officers will revise the lists, accept challenges, and prepare the final voters rolls that polling stations will use on election day. The EXTRA edition exists for one purpose only: to make the scale of these federal by-elections transparent the instant the preliminary lists close.

Just twenty-four hours later, the regular Saturday edition (Vol. 160, No. 11) of March 14, 2026, continued the official record with an array of regulatory actions that affect industry, the environment and public appointments across the country.

Strict Ministerial Conditions Imposed on Hazardous Chemical

Under the Canadian Environmental Protection Act, 1999, Ministerial Condition No. 22313 now governs the substance phenol, methylstyrenated (Chemical Abstracts Service Registry Number 68512-30-1). The Minister of the Environment permits manufacture or import only when the substance is used as a component in adhesives applied in one of two tightly controlled ways.

First, the adhesive must be sprayed inside a booth or enclosed area designed to capture all overspray, with every waste stream collected. Second, it may be used for minor maintenance and repair in quantities that never exceed 10 kilograms of adhesive per day per site. The notifier may transfer possession only to persons who agree in writing to obey the identical restrictions.

Before any manufacturing begins in Canada, the notifier must give the Minister 120 days’ written notice and supply exhaustive details: projected annual quantity, exact facility address, transportation and storage methods, container specifications, anticipated environmental releases, wastewater discharges, destruction methods, full hazard data, exposure-limiting factors and a complete manufacturing-process description including flow diagrams and reaction stoichiometry.

Waste disposal is equally prescriptive. Every container or vessel must be thoroughly rinsed before disposal or reconditioning. All waste, including effluents, rinsates, disposable vessels, spillage and residuals, must be either incinerated according to local law or deposited in an engineered hazardous waste landfill facility. Any accidental environmental release triggers immediate containment measures and notification to the provincial 24-hour emergency line.

Record-keeping obligations run for five full years after creation. The notifier must log every use, quantity manufactured or imported, every transfer of possession, every disposal transaction and every written confirmation received from downstream users. Records must remain at the principal Canadian place of business in readable electronic or paper form, in English, French or both. The conditions came into force February 19, 2026.

Plastics Registry Reporting Extended for 2025 and 2026

The same edition amends the earlier Federal Plastics Registry notice. Producers of packaging, electronics and electrical equipment, and single-use or disposable plastics headed for the residential waste stream must continue reporting for calendar years 2025 and 2026. The Minister of the Environment, Julie Dabrusin, also signalled intent to issue a fresh notice covering 2027, 2028 and 2029, with stakeholder consultation to follow.

Saskatchewan Wastewater Agreement Now Official

Two notices under the Fisheries Act confirm that the administrative agreement between Canada and Saskatchewan for the Wastewater Systems Effluent Regulations is complete. No public comments were received during the 60-day period, and the final text is now available on the Environment and Climate Change Canada website.

New Radio Standards Published for Fixed Systems

Innovation, Science and Economic Development Canada released two updated Standard Radio System Plans: SRSP-300-Gen, issue 2 (general technical requirements for fixed radio systems above 960 MHz) and SRSP-301.7, issue 5 (specific requirements for the 1700-1710 MHz and 1780-1850 MHz bands). Both documents are now official and available on the Spectrum management website.

Governor in Council Appointment Opportunities Open

The March 14 edition also lists current vacancies open for applications on the Governor in Council appointments website. Positions include Director of the Canada Infrastructure Bank (closes March 16, 2026), Director of Canada Mortgage and Housing Corporation (March 16), Director of Canada’s National Infrastructure Crown Corporations (March 16), Commissioner of the Canadian Energy Regulator (March 13), Chairperson of the Canadian Museum of History (March 19), Director and Master of the Mint at the Royal Canadian Mint (March 19), and several commissioner and director roles at the Office of the Commissioner of Indigenous Languages.

These parallel publications, one EXTRA and one regular, illustrate the Canada Gazette’s dual role: spotlighting the democratic machinery of federal by-elections while simultaneously updating the regulatory framework that governs chemicals, plastics, wastewater, radio spectrum and public appointments. Every Canadian now has the official numbers, the binding conditions and the open opportunities in a single, authoritative record.
