How did the quebec act of 1774 contribute to the foundations of Canada as officially bilingual country?

One of the key measures within the Quebec Act of 1774 was the restoration of French civil law (which had been eliminated in The Royal Proclamation of 1763), while maintaining British criminal law. This had the practical effect of requiring much of the region's business be conducted in French, as the domain of civil law reaches from family law, to inheritance issues, property and contract law. An additional effect of the Quebec Act in relation to Canadian bilingualism was to reaffirm Quebec's strategic and economic importance to British North America as a whole through the restoration and expansion of lands that had also been diminished under the Royal Proclamation of 1763. In the long term, both of these measures established in the future Canada a respect for the contributions of the French and an appreciation of their culture.
