I like the small towns in Canada, preferably one with karaoke.

I like to stay at hostels, home hospitality or hotels. I have a license but no car

Ok here is my suggested route:
Winnipeg-Kenora
Kenora-Fort Frances
Fort Frances-Thunder Bay
Thunder Bay-Pukaskwa National Park
Pukaskwa-Agawa Bay
Agawa-Sault Ste-Marie
Salut-Sudbury
Sudbury-Temiskaming Shores
Temiskaming-Val d'Or
Val d'Or - Mont Tremblant
Mont Tremblant - Shawinigan
Shawinigan - Chicoutimi
Chicoutimi - Tadoussac
Tadoussac - Baie Comeau
Baie Comeau (ferry) - Percé
Percé - Bathurst
Bathurst - Shediac
PEI is option to visit here (3-4 days on the island)
Shediac - Pictou
Pictou - Baddeck (stay for a few days to see Cape Breton Highlands)
Baddeck - ferry from North Sydney to Port aux Basques, probably stay near Corner Brook
Corner Brook - Gander
Gander - Dildo
