To be honest your post has me a tad confused… but that is mostly because I am a Canadian, and I don’t know where you are (cause you don’t have a location in your PROFILE Info at the top of your post). So I don’t know if you are asking this particular Question as a Canadian or as someone who resides in the USA.
October 11, 2014 is a Saturday, on the Canada’s Thanksgiving Weekend (2nd Monday in October)
In Canada, Thanksgiving isn’t quite the same big of a deal as it is in the USA.
Here Thanksgiving although “officially falling on the Monday”, most Families tend to have their Thanksgving Meal at whatever point in the Weekend is convenient… be that anywhere between the Friday Night to sometime on the Monday.
It is a time when Canadians go for drives in the countryside to see the leaves, maybe get in a hike, or a last camping trip… close their Cottages, Clean Up their Yards, Decorate for Hallowe’en (and hang Christmas Lights), and do other chores outside around the house, and outdoor activities.
There is “some Football” (CFL) – “some Hockey Games” – but not much in the way of Homecoming Events … and definitely NO BLACK Friday.
Consequently, it isn’t like in the US where they say more families get together / gather than even Christmas (Christmas is bigger here, cause Thanksgiving is just one day off, where for Christmas we get a lot more Stat Holiday time than our US neighbours)
Thanksgiving here is the official end of the better weather season… and people tend to do things that are low key and enjoy the fact there is an “extra day” to enjoy doing whatever is on their MUST DO BEFORE IT SNOWS LIST
I have gone to Thanksgiving Weddings in Canada before… they are great. The added bonus of the long weekend to travel is nice. And it is usually FANTASTIC Fall Weather… and if you are in the East… Ontario thru to the Maritimes the leaves in colour are usually fantastic !!
So ya, if you are planning a Wedding for Canada’s Thanksgiving Weekend, I say… GO AHEAD it will fabulous.
Now if you are an American, and looking at THAT THANKSGIVING which happens in Late November then I think you are facing a whole different ball of wax in regards to cultural impact (and Weather if you are in a more Northern State)
I would think that you’d get a lot fewer attendees having your Wedding fall on that weekend as Americans seem to make a TON OF PLANS for their Thanksgivings, where us Canadians are a lot more “free flowing / easy going” for that Holiday.
Hope this helps,
