It's the last weekend of the summer and with some warm temperatures in the forecast, it's a great weekend to get out of the house and explore.

If you want to go for a drive, maybe see if the leaves are changing around Waterloo region, you could take in the fall fairs in Lucknow, Ancaster, Stratford or Grand Valley.

This Saturday is Doors Open Waterloo Region. This year's theme is water and the event gets underway early with a special ceremony by the Grand River.

You can also get into the Oktoberfest spirit early with a pop-up sale at Concordia Club — for all your dirndl and lederhosen needs.

There are several events taking place in Guelph as part of the Global Climate Strike, including daily noon-hour talks at St. George's Square, Vegfest at Riverside Park on Sunday and a workshop in Joseph Wolfond Memorial Park Sunday afternoon on how to grow native plants around your own home.

And if you have a sweet tooth, the Great Canadian Buttertart Fest is happening in Paris.
