1. The Bank of Canada raises rates (October 28)

The Bank raised its policy rate by 25 basis points to 2.5%, its first increase since 2023. It expects inflation to reach about 3.5% by the end of 2026 and return to 2% around mid-2028, and said its surveys point to more cost pass-through by businesses over the next year. For owners: higher carrying costs and contractors more willing to pass on price increases. The next decision is December 9. More in our rate hike post.

2. Bill 140, the Building Ontario Faster Act (October 27)

Ontario’s bill passed first reading. The province says it could save nearly 220,000 days of combined permit processing time, with archaeological approvals up to 80% faster, a digital map of underground infrastructure and a faster route for the Highway 69 widening. Comments on the Highway 69 and landfill proposals close November 26. For owners: promising, but not law yet, so keep current approval durations in your schedules. More in our Bill 140 post.

3. Ottawa matches Ontario’s $1 billion for the Ring of Fire road (October 21)

Prime Minister Carney committed $1 billion to road construction into the Ring of Fire mining region, about 500 km north of Thunder Bay, matching Ontario’s pledge. It came as part of an $8.7-billion federal-provincial plan for tariff-affected industries such as steel and autos. Construction on two roads began this summer; several First Nations support the road and others oppose it. For owners: another large, long-running northern program that will draw on heavy civil contractors and crews.

4. New councils across the GTA (October 26)

Toronto re-elected Olivia Chow; Brampton, Vaughan, Markham and Richmond Hill returned their mayors. Mississauga, Hamilton, Oakville, Milton, Halton Hills, Caledon and Clarington chose new ones. For owners: new councils will revisit development charges, approvals and land-use priorities. Toronto’s 40% to 60% development charge cut for 2026 to 2029, tied to up to $1.5 billion in federal-provincial funding, is one to watch in the new council’s first budget.

5. Contractors fill up and consolidate (October 26 and 29)

Aecon reported third-quarter revenue up 26% to $1.92 billion and a record $14.6-billion backlog, up from $10.8 billion a year earlier, after about $6 billion in new awards including its $1.75-billion share of the Pickering nuclear refurbishment. Limen Group agreed to acquire York1’s civil infrastructure and demolition businesses, and earlier in the month Pomerleau, WSP and Englobe all announced acquisitions. For owners: expect fewer tier-one bids and less appetite for risk on mid-size projects. Test bidder interest early and size packages for the next tier of contractors.

6. U.S. tariffs shift again (October 20 and 30)

An importer filed the first legal challenge to the U.S. Section 338 tariffs on Canadian goods on October 20. From October 30, the 50% list dropped plywood, plastic wrap, cardboard boxes and food-related machinery, and added paints, MDF, carpets and rugs, and air conditioners. For owners: finishes and HVAC suppliers face new pressure. Ask bidders where those items come from. More in our import exposure post.

7. A transformer supply plant for Ontario (October 16)

Hitachi Energy announced a $479-million factory in London, Ontario, to make transformer pressboard insulation, with $50 million in combined federal and provincial support. Construction has started, but the plant is not expected to be ready until late 2028. For owners: good news for the domestic grid equipment supply chain, but no relief for transformer lead times on projects tendering now. Order long-lead electrical equipment early.

8. Infrastructure Ontario keeps social infrastructure moving (October 27 and 30)

IO awarded EBC a $178-million fixed-price contract to expand the Quinte Detention Centre by 91 spaces, with construction expected to start later in 2026. It also issued the RFP for Contract 1 of Windsor Regional Hospital’s Fancsy Family Hospital, a five-storey diagnostic and treatment block delivered as design-build-finance-maintain. Two teams are bidding: one led by EllisDon with Parkin Architects, and one led by Plenary with B+H Architects, Sacyr and Amico. For owners: public hospital and justice work continues to absorb major contractors and design firms through 2027.

9. Market data: permits up, investment flat (October 14 and 21)

August building permits rose $1.1 billion to $13.6 billion, driven by multi-unit residential, while non-residential permits slipped to $5.1 billion. Investment in building construction edged up 0.1% to $23.5 billion, with non-residential up 1.0% and Ontario multi-unit residential down $79.4 million. The Canadian Construction Association reported non-residential costs up 3.5% year over year and steel-intensive divisions up more than 8%.

Multi-unit homes led August permits Building permit values by type, August 2026, $ billions: Multi-unit residential $5.8B; Single-family $2.6B; Commercial $2.2B; Institutional $1.8B; Industrial $1.1B.

10. Design and architecture: pre-approved homes and a national residence

Toronto added free, pre-approved fourplex and sixplex designs, prepared by an architecture firm chosen through a competitive procurement, that let owners go straight to a building permit when zoning is met (October 2). The campaign to restore 24 Sussex Drive, the prime minister’s residence, through a national design-and-build competition passed $5.7 million in donations toward its $50-million goal (October 28). For owners: standardized, pre-approved designs are a practical way to cut approval time on repeatable building types.

What to do in November

  1. Update financing assumptions for the 2.5% policy rate before the December 9 decision.
  2. Test bidder appetite early and keep packages sized for the next tier of contractors.
  3. Order long-lead electrical equipment now. New domestic supply won’t arrive before late 2028.
  4. Check sourcing for finishes and HVAC on tenders closing this quarter.
  5. Brief your board on the new councils and read the federal budget on November 5.

The bottom line

October’s news points one way: higher costs and busier contractors now, faster approvals later, and new local decision-makers in between. Owners who update their assumptions this month will have fewer surprises in the spring. Want a second look at how October’s changes affect your program? Book a 30-minute call.
