It is highly unlikely that you are a British citizen by descent.
British citizenship (and I believe Canadian citizenship as well) can only be passed on to one generation born overseas. As your grandparents were born in the UK, your father, though born in Canada, was also a British citizen by descent. However, a British citizen by descent can not pass on his citizenship to his children, unless they were born in the UK.
These are the broad principles of current UK citizenship law.
To help you further, can you provide us with your father's and grandparents year of birth? And were your grandparents married at the time of your father's birth? Similarly, were your parents married at the time of your birth? UK citizenship law has evolved over time and the questions above are to look at if older provisions of the law may apply.
You are, as you mentioned, eligible for the Ancestry visa based on the citizenship of your grandparents.
