 | Southern Terminus: | SH-602 , 13km southwest of Fort Frances |
| Northern Terminus: | Terminus, 13km north of Hwy 11/TCH |
| Length: | 20 km |
| Notes: | As likely as it may seem, SH-611 does not derive its designation from the fact that it intersects, and even runs concurrently with, Hwy 11, but rather due to the general secondary highway numbering pattern in the area. |

| Notes: | In a previous spat of downloading several years ago, the southern portion of SH-612 through MacTier to Hwy 69 1.7km west of Foots Bay was downloaded onto Muskoka DM, thus creating a spur-route ending at a political boundary. |

| Northern Terminus: | Fraserdale on the Ontario Northland Railway |
| Length: | 76 km (approximately) |
| Notes: | As of this writing, it is unclear as to this highway's precise southern terminus. Traditionally, SH-634 had ended at Hwy 11/TCH in Smooth Rock Falls, but the highway was realigned to bypass much of the community to the east within the past few years, still ending at Hwy 11 east of town. However, some of the latest sources the portion of SH-634 within the limits of the Town of Smooth Rock Falls may have been downloaded, creating another "detached" highway--one which is no longer contiguous with the rest of provincial highway system. |
