Updated October 21 at 4:20pm: The TTC posted an updated map and table of RSZs dated today. Information on the map and tables now match. There are only 9 active slow zones with target removal dates through to late November. The October 21 versions have been added to the end of this article.
Updated October 17 at 11:00pm: The TTC posted an updated map and table of Reduced Speed Zones dated October 17, but the info on the map is still out of sync with the info in the table of slow zones. The revised version is at the end of the article.
In previous articles, I have reported on the number, location and longevity of reduced speed zones on the subway. See:
A recent problem with the TTC website page where these are reported is that information is inconsistent between the map showing problem areas and the tables explaining each problem and its expected resolution.
Here is the current version of the RSZ map dated October 16 at 10:16am.
Here is the text describing these zones:
There are several inconsistencies between the current map and tables.
The statement that there are 13 zones appears to be based on the count of table entries. Note that for a “bothways” restriction, they count as two. Listing only a single direction in the table undercounts the number of locations. In this case the count, based on the same premise, should be 18 not 13.
In past versions each direction has counted independently, and in some cases more than one location was flagged in a track section (marked “X2” below).
There is a further problem if we compare the claimed completion dates with information shown on September 5.
There are definitely more entries in September than in mid-October, and so the TTC has been working away at these issues. However, the projected dates have drifted in many cases.
| Location | On Map | In Table | Target as of Sept 6 | Target as of Oct 16 |
|---|---|---|---|---|
| Yonge SB Eglinton to Davisville | Yes | Yes | Mid Sept | Early Nov |
| Yonge NB Union to King | No | Yes | Early Nov | |
| University BW St. George to Spadina | Yes | No | ||
| Spadina BW St. Clair West to Eglinton West | Yes | SB Only | Early Sept (NB) | Late Oct |
| Spadina BW Glencairn to Lawrence West | Yes | Yes | September | Late Oct |
| Spadina SB Yorkdale to Lawrence West | Yes | Yes | Mid Sept | TBD |
| Spadina BW Sheppard West to Wilson | Yes | Yes | TBD | TBD |
| Bloor Kipling to Islington BW | Yes | EB Only | TBD (WB) | TBD |
| Bloor Old Mill to Jane BW | Yes | WB Only | Mid Sept (WB) | Late Oct |
| Bloor Bay to Yonge BW | Yes | EB Only | TBD | |
| Danforth Donlands to Greenwood EB | Yes | Yes | Mid Sept | Late Oct |
| Danforth Warden to Kennedy BW | Yes | EB Only | Late Oct |
The TTC needs to adopt a consistent way of reporting reduced speed zones, counting how many are active and projecting credible target dates for remediation. As thing now stand, the information in the maps and text differs, and the count of RSZs appears to be lower than what is actually in effect. In turn, this allows management to “hit” a lower target by under-reporting problems, and this is precisely the sort of behaviour that has bedevilled the TTC’s performance metrics for years.
Updated October 17 at 11:00pm: Here are the October 17 versions of the RSZ map and tables. The TTC still appears to be incapable of posting consistent data. On the bright side, some of the zones that had “TBD” target dates on October 16 now have October or November dates.
Updated October 21, 2025
Here are the current versions of the map and tables with the information now back in sync.
