| 1336 | +# # Thunder Bay skipped DST in 1973. |

| 1338 | +# # Nipigon (EST) and Rainy River (CST) are the largest that we know of. |

| 1340 | +# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom |
| 1341 | +# right corner of page 1, it says that Toronto will return to standard |
| 1342 | +# time at 2 am Sunday morning (which agrees with the database), and that: |

| 1344 | +# The one-hour setback will go into effect throughout most of Ontario, |
| 1345 | +# except in areas like Windsor which remains on standard time all year. |
| 1346 | +# |
| 1347 | +# Windsor is, of course, a lot larger than Nipigon. |

| 1349 | +# I only came across this incidentally. I don't know if Windsor began |
