FYI the various issues with Maine, were lack of Frequency availability, not too much to do with Canada.
The lack of VHF frequencies, allowed them to petition the FCC and NTIA for access to the Part 22 [Paging], NTIA [Federal]
and the AAR Part 90 [Railroad] channels, which explains the MSCommNet use of 150-174 in its entirety

I mostly encountered a 10 MHz offset for repeaters in the 378-400 band.
HOWEVER..... In some areas, other offsets were used on a frequency by frequency basis. Usually when coordinating with Mexico and Canada. In those situations, at a single RF Site, some repeaters might be a standard 10 MHz offset, and other offset pairings might be what can be accommodated, and look bizarre to someone not familiar with the situation.
BTW:
Motorola has major headaches on the NCR system were all the frequency offsets at a single site were not the same exact offset.
For some weird reason, Moto software (at that time) couldn’t accommodate different repeater offsets for the same site.
All of them had to be 10 MHz, or 12 MHz, or whatever.
Sites were Repeater 1 was 10 MHz offset, and Repeater 2 might be a 13.2 MHz offset was outside of their ability for several years.
(I also ran into some wild repeater frequency pairings for repeaters on VHF-Highband on the State of Maine P-25 system, to de-conflict with Canada.)

Generally by rule it is + 10 Mhz
