There certainly must have been some opposition in Colombia, since the land where the canal was built was taken away from that country and given to Panama.
Since a previous attempt to build such a canal by France failed, there must have also been some opposition to the cost as well.
Those are answers off the top of my head. I suggest you do a search and read some references on the subject.
Theodore Roosevelt wanted to build a canal in Central America. Why was there opposition to Roosevelt's plan?
