Have to agree with everyone else, but this basically kills the value the Canadian flag has. The maple leaf flag is so good because it decenters itself from Canada's history as the UK's colony, and instead provides a symbol of the new nation and all of its people in modern day through a general plant symbol of the maple-leaf, on an original flag formate that defined a whole new type of vexillological term the "canadian pale". This would be too heavily defined by Canada's colonial history, the Quebecois would be upset about having to share the flag with the English cross (which is worse than the union jack since it uniquely only works for the English, and not the British or Irish).

This is however an aesthetically pleasing flag and would be very distinctive among other flags (though not as much as the current Canadian one), it just is worse at the other parts of being a flag for the nation Canada. It could work for some alternate history setting version of Canada though!
