Looking for angle/thesis statement to approach essay/Prime Minister John A. Macdonald

I am having difficulty narrowing down ideas for a thesis statement on Prime Minister John A. Macdonald. If anyone is knowledgable in the area of Canadian history and might be willing to help it would be greatly apreciated.

Some things about Prime Minister Macdonald:

-United Canada
-Was a drunk
-Built the Canadian Pacific Railway
-first prime minister of Canada
-born in Glasgow Scotland
-family immigrated to Kingston in 1820
-rebellions made him a lawyer
-knighted by Queen Victoria

*I was leaning towards the idea of: Would Canada be the nation it is today without John A. Macdonald.

Any help is appreciated, even if you can help me elaborate the thesis i presented above.

Thank You!

I think that is a good start but I would suggest to make a brief introduction of who he was instead of asking the reader of who he was. This might be a good idea so that the reader can either recap on what they know about him already or if they arn't aware of who he is, then they can get an informative yet very brief discription of who he was in the thesis statement. For example: John A. Macdonald was a memorable indivisual in Canada's society because of the important deeds that he did and the accomplishments that he made. I hope this helped

Thanks a lot, apreciate your input.
