A week is not going to cut it so you need to narrow your focus.
where are you travelling from? land sea or air?
What time of year?
What are you interests?
A cottage on a quiet lake (Haliburton highlands north east of Toronto)
Old world charm? (Quebec City)
Big lights? Montreal, Toronto (musicals, sports) or Vancouver (or as Foxy himself calls it...Hongcouver)
Wilderness. Rockies west of Calgary
Down home friendliness? all of the Atlantic provinces ...New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland (the latter would take at least a week to do properly but it truly is unique....search the musical "Come From Away" to see who Newfies are all about)
