You're correct in your analysis and in trying to bring out the important role the federal government has in leading the way when it comes to legislation and creating a fairer society for all Canadians. When the Supreme Court rules that the right to strike, the right to collective bargaining and the right to freedom of association are charter rights, that should trickle down not only at the federal level but into the provincial jurisdictions as well. Just as with minimum wage and other progressive labour legislation adopted at the federal level, provinces often fall in line.
It's absolutely key to creating the conditions for provinces to take up a ban against replacement workers.
