To "join" implies that two entities existed separately, and then became one. While Alberta and Saskatchewan became provinces on September 1, 1905, it was because they were created out of the Northwest Territories by the Government of Canada. These provinces did not exist as separate entities before September 1, 1905, and therefore could not "join" Canada. It is better to say that they "entered Confederation" on September 1, 1905.

Your question is very unspecific. BC required a railway, but much of the Prairies were HBC lands that were signed over to the crown and eventually divided into provinces in 1905. A much smaller Manitoba under the leadership of Louis Riel was the only other western area that joined confederation in a manner similar to the Eastern provinces. Ask a more precise question. ------------- Canada West is not the same as Western Canada. Canada West is also called Upper Canada. So the question is asking what were the negatives or reasons for Canada West or Upper Canada to not join in the United Province of Canada with Lower Canada. They did join and the Province of Canada went on to have other provinces and colonies join in a Confederation that the Province of Canada (Ontario and Quebec) dominate today. Reasons for Upper Canada to not join include having to give up some rights of self control. Also Lower Canada was Catholic and French while Upper Canada was Anglican and English and they did not always get along as well as they do today.
