Not by default — and skipping notice can undo whatever the board decided.
Short answer
Not without checking your by-laws first. The Condominium Authority of Ontario's guidance sets a 10-day default notice period for board meetings, which the corporation's own by-laws can shorten or lengthen. That is a different regime from the annual general meeting, which owners attend — a board meeting is directors-only, with its own quorum and notice rules.
Per the Condominium Authority of Ontario: “directors must receive a notice at least 10 days before the board meeting unless by-laws specify otherwise,” and “the notice must include the time, format, instructions for joining and the topics for discussion or voting.” The 10-day figure is a default, not a hard statutory floor — the first thing a board should check is its own corporation's by-law, not the general rule.
CAO draws a clear line between the two meeting types: “typically, only board members attend but guests can be invited to discuss specific topics and could include unit owners, tenants, vendors and more,” whereas an annual general meeting is open to owners as a matter of course. Quorum for a board meeting is “more than 50 percent of directors being present,” and “a director attending the meeting virtually or by phone is considered present for the purpose of quorum.” CAO's guidance does not spell out a stated legal consequence for a meeting held without proper notice, but two practical risks follow regardless: a director who wasn't notified and didn't attend can challenge what was decided, and any owner who later requests the minutes — boards “should be prepared to share these minutes with owners if they get a records request” — will see a meeting with no evidence proper notice went out.
A five-director board needs to approve a $12,000 emergency roof repair after a leak. Two directors are reached by phone the same day and show up; the other three get no notice at all. Two of five directors present is 40% — below the “more than 50 percent” quorum threshold on its own, so the vote fails on quorum grounds before the notice question even needs to be argued. Had all five been notified per the corporation's own by-law period and three attended, quorum would be validly met.
Confusing board-meeting notice rules with AGM notice rules. They are two separate CAO regimes with different audiences — directors only, versus all owners — and different purposes: routine governance versus the annual meeting and election structure. Treating them as one rule is the most common mix-up boards make.
