Eight Ontario opportunities with electrical scope close between Monday, November 2 and Friday, November 6. Three of them are prequalifications, which decide who gets to bid the real work later. Next week also brings a hard deadline on a bigger job that closes later in November.
Every bids&tenders item below was checked as Open on its public page on Thursday, October 29, 2026, and the plan-taker counts are from that check. Times are Eastern as the portals show them. Addenda can move a date, so confirm on the buyer page before you submit.
Deadlines before the closings
- Monday, November 2 at noon: questions for Peel's Clarkson clarifier job, 2026-229T, and for Hamilton's Woodward Avenue prequalification, C14-04-26.
- Monday, November 2: names for the mandatory job walk on the Toronto Port Authority's port electrical infrastructure rehabilitation, 2026-150-06 on MERX. The walk is Wednesday, November 4 at noon, with a limit of two people per proponent, and the notice says photo ID and safety gear are required. The RFP closes November 19, but skip the walk and you're out.

How to use this list
Send the Port Authority your job-walk names by Monday, before you do anything else on this list. The three prequalifications from London, OCDSB and Hamilton don't win you work this week, but they decide whose bids count later. If you're a sub on Peel, Mississauga or Brampton, call the plan takers early in the week, before their numbers lock. bids&tenders preview pages are free, but secured documents usually need a registered account.
