The Toronto Star had their reviewers pick Canadian books they think are must-reads: https://www.thestar.com/entertainment/books/2017/06/30/15-books-for-canada-150-our-reviewers-choose.html.
The Kingston Writer’s Fest asked people to nominate Canada's 150 Best Books Picks. Here’s the complete list: https://www.kingstonwritersfest.ca/150-2/.
BookNet Canada pulled together a list of 150 Canadian-authored (English language) bestsellers from the last 10 years: http://www.booknetcanada.ca/blog/2017/6/13/150-bestselling-books-by-canadian-authors?utm_content=buffer080df&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer.
Last year on Canada Day, I referred to CBC Book’s List of 100 Novels that Make you Proud to be Canadian: http://www.cbc.ca/books/books100.html. That list is still a good one.
My favourite list, besides my own, is the one compiled by 49th Shelf. 150 Canadian authors were asked to recommend their favourite Canadian book: https://49thshelf.com/150-for-150.
When choosing your next book to read, you might want to peruse these lists. Maybe choose a title that appears on more than one list?
