Our Annual Brochure

Our annual brochure provides information about our current season's lectures and our awards program for teen-age prose writers, poets, scientists and musicians. It also lists the Association's officers and other members of our Executive Council, and briefly summarizes the Association's long history. The brochure also provides essential contact information.

The brochure for our 2022-2023 season was mailed in early August to current and past members and those among the Association's friends who have provided their postal address.

A downloadable, printer-friendly version of the brochure is available on our Annual Brochure page.

The brochure is also available for pickup at our public lectures.


When and Where


Each lecture will be presented on a Saturday evening starting at 7:30 pm. 8:00 pm. Note the later start time compared to our previous season.

Each lecture will begin with the President's welcome and the introduction of the evening's presenter. The latter will speak for about 50 minutes. A question and answer (Q&A) period will then follow. The duration of the Q&A period depends on the number of questions.

Audience members will be able to submit questions to the evening's Questions & Answers (Q&A) Manager during both the presentation and the Q&A period. Instructions on how to submit a question to our Q&A Moderator are provided in our emails to those who have registered for a given lecture and on our FAQs page.

Each evening will end by about 9:00 pm,9:30 pm. Presenters often stay for a few more minutes in order to answer additional questions from audience members one-on-one.


All lectures in our 202Y1–20Y2 season will be presented online, in "webinar" format, via the Zoom website. If you are unfamiliar with Zoom or Zoom webinars, with registering for our Zoom events, with joining a Zoom broadcast already under way, or you are a presenter who wants to share your screen with the audience, visit our Zoom FAQs page at: www.haalsa.org/faqs-zoom.htm.

If you are unable to join us for the live broadcast, you will usually be able to watch the webinar a few days after the event via the lecture's "Watch the Video" link, which we will display as soon as the video file becomes available. (This assumes, of course, that our presenter consented to our recording their lecture.) That link will be valid for at least 15 days.

Except where noted above — see 5 April — each lecture will be presented in Room 1A1 of the Ewart Angus Centre (EAC).

The Ewart Angus Centre is an area in the north-west (left-rear) corner of the McMaster Children's Hospital on Main Street West. (The hospital is also known as the McMaster site of the Hamilton Health Sciences Corporation, the McMaster University Medical Centre or simply as MUMC. See our Campus Map.)

The EAC is wheel-chair accessible. Enter either via the Centre's front (west ) or rear (east) ground-floor doors or via the corridor that runs to the rear of the hospital building, through the Red and the Purple areas. If entering the hospital via its front (Main Street) doors, turn left, go down the corridor, and take a Red elevator down one level to Floor 1. On exiting the elevator turn left, go past the Media Centre (book store) and carry on to the Purple elevators and into the open space just beyond that. That's the Centre's lobby.

From the EAC Lobby to Room 1A1:

  • If you enter the hospital building via the rear (north-end) doors facing University Crescent, you are already in the Ewart Angus Centre. Carry on into the lobby itself and go down the short corridor that begins on your left, opposite the William's Cafe outlet.
  • If you enter the hospital building via the rear (north-end) doors facing the building's inner courtyard, you are already in the EAC lobby. Go past (not up) the staircase and enter the short corridor on your right, opposite the William's Cafe outlet.
  • If you enter the EAC lobby via the corridor that ends at the Purple elevators, turn left on entering the lobby, walk to the end of the William's Cafe outlet, turn right, and go down the short corridor you see before you.
  • Room 1A1 is on your right at the end of that short corridor. There'll be signs to assist you.

Parking On and Off the McMaster Campus


We suggest that you not park in the Hospital's underground or surface lots. In July 2022 the rates (Monday through Sunday) were $4.00 and $4.50 per half hour or less to a daily maximum of $21 and $26 for the underground and surface (emergency/short term) lots respectively (MCH's rates).


There are many off-campus parking spots on Stirling and some of the adjacent streets, including streets south of Stirling down to but excluding Main Street West.

Spots are usually unrestricted on Saturday evenings along most streets in the area near McMaster campus. Nonetheless, before leaving your vehicle, read carefully the city's signs regarding on-street parking. And of course, before leaving your vehicle, ensure that any valuable objects are locked in your trunk or otherwise not visible to prying eyes.


For vehicle access details see our Campus Map and associated instructions.

McMaster University provides no free on-campus parking at any time. The charge for any gated lot and metered parking spot entered on a Saturday is a one-time payment which is valid until at least midnight. You pay when leaving a gated lot or when obtaining your ticket from an on-street meter. Payment is by credit card only.

The last time we checked (15 Aug 2022), visitors without a transponder or seasonal parking permit may park for $8.00 in gated lots A (Divinity College), B, C, D, I G, H, Underground Wilson, Underground Stadium,or in a metered on-street parking spot. All gated parking lots are located farther from the Ewart Angus Centre than the two on-campus bus stops nearest the EAC.

Metered on-street parking spots are available on the east side of College Crescent, next to the Bourns Science Building and the John Hodgins Engineering Annex. Note the permit dispensers at regular intervals along the sidewalk.

Our understanding is that Parking Services' enforcement of the metered on-street parking rules is lax or non-existent on Saturday evenings after 7:00 pm. In the past some members have parked in one of the on-street spots on College Crescent, not purchased a permit from the nearest meter, and not been ticketed.

One final caution:  Do not park in a designated fire route, such as behind or beside the Ewart Angus Centre, or a spot reserved for disabled persons and those with accessibility issues, unless of course you have an up-to-date Ministry of Transportation Accessibility Permit for such spots. You risk being ticketed and towed for either offense.

The Association is not and will not be held responsible for any parking ticket you might receive.


If Coming By Bus


There are on-campus HSR bus stops on University Avenue near the Ewart Angus Centre and off-campus stops on Main Street near and opposite the Medical Centre. The on-campus stops nearest the EAC are within comfortable walking distance of the Centre's main entrance. As noted above, the EAC is in the purple area (north-west corner/rear) of the Medical Centre.

For up-to-date HSR route information, however, telephone the HSR at 905-527-4441 or follow the links on the HSR website (https://www.hamilton.ca/hsr-bus-schedules-fares/schedule-routes-maps"). For bus stop details see our Campus Map and associated instructions.
