A trench through the town would still create many of the same dentrimental effects on the community (and would again be expensive due to rocky terrain). I imagine the original VIA plans put a station in Sharbot Lake precisely because they knew there was no way to get the line through the area without causing massive local disruption so they needed to give something to the locals in exchange.
Looking at the line though, it seems that none of the other hamlets present nearly as big of a problem as Sharbot Lake. The ROW through Tweed has been built on (there's a residential street taking up the former route) but a bypass of that village would be easy enough. And for other towns on the abandoned ROW section of the line, like Kaladar and Arden, the ROW doesn't really disturb anything if restored.

We aren't just talking about bypassing Sharbot Lake. I'm thinking they need a new alignment right through. Whether they go through the town or around them will be up to the developers.
A few years ago, a transit blogger (Ontario Traffic Man) looked at the realignments necessary to achieve VIA's goal of getting from Union to Ottawa in under 3 hrs. Here's their map for the stretch we are discussing:
And their look at the portions that could theoretically be upgraded to 110 mph/ 177 kph:
With all those upgrades and the high speed alignment they designed between Kaladar and Perth, they still couldn't get Toronto-Ottawa to under 2.5 hrs:
Some quick math suggests they need to design something that allows for an average running speed of about 256 kph between at least Norwood and Perth. The
Avelia Liberty about to be deployed on the Acela Express has a planned service speed of 160 mph / 260 kph and a top speed of 186 mph / 300 kph with tilting. So I think if this is the bid, then Alstom would propose a fully new alignment between Peterborough and Smiths Falls that covers that distance in 40 mins. And what do ya know, that's what Alstom suggested in their recent public pitch:

Alstom's proposal still doesn't consider things like speed restrictions in suburban sheds of the major cities or the requirements to stop in Casselman or Alexandria. But I think their proposal is probably closer to 4 hrs all stop (Toronto to Montreal) and 3 hrs express with stops at only the downtown stations (Ottawa and Montreal).
