Yes, though more accommodating than one would expect in a time of rampant sectarianism.

After the fall of Quebec and the capitulation of French forces in 1759-60. Quebec was under British military occupation until the end of the Seven Years War. There were expectations esp. among the New England merchant class who migrated there after the conquest that they would fill the power vacuum. They hoped to assert their "rights as Englishmen" aka enjoy their privileged status as Protestants and disenfranchise the majority Catholics in Quebec. The British initially intended for Quebec to be wholly assimilated, hoping that massive English Protestant migration from the Thirteen Colonies may one day supplant the local habitant populace.

(French subjects outnumbered the English in Quebec by 25 to 1, a huge factor in British planning for its governance.)

The military (later, civilian) governor James Murray did not like the New England merchants' demands for special treatment and entitlements. British authorities had little desire to grant them an assembly such as those in the Thirteen Colonies. As no Catholics could run for public office, it would have been dominated by Protestants. He grew to prefer working with Quebec's former elites: the landowners, the Catholic Church, etc. This policy of tolerance continued with Murray's successor, Guy Carleton.

The British had previously captured the island of Minorca from the French during the wars and thus had some recent experience in accommodating Catholics. These lessons would soon become useful in ruling Quebec. Language, religion and property rights would be granted to the French in Quebec. Restrictions on Catholics in public office remained (and the highest offices remained the domain of English Protestants), but allowances were made to permit the previous seigneurial system to remain, which even enhanced the landowners' status and local Catholics could hold minor administrative offices.

The Catholic Church still faced discriminatory treatment in public life and religious orders esp. Jesuits were suppressed. But gradually, British authorities found more common ground with the colony's Catholic hierarchy bc it was seen as a more effective way to win over a leery and mistrustful population. While the oath of loyalty was still required to serve in minor public offices, the references that required the disavowing of Catholicism were removed from the oath. The Church was also granted the ability to collect tithes. These accommodations were generous and unheard of in the rest of the Empire, enraging the New England merchant class.

When these accommodations were enshrined into British law with the 1774 Quebec Act, it was viewed as intolerable in the Thirteen Colonies, who were virulently anti-Catholic and had disparaged French culture. While these protections ensured that Quebec's residents would not join the rebels in the American Revolution, it didn't encourage them to fight for Britain either. They saw neutrality as the prudent course. The population was still skeptical and trusted the Patriots even less than their British rulers.

In the aftermath of the Revolution, some 60,000 Loyalists left the US. About half of them moved to Canada. Most went to the Maritimes, compelling Britain to create the colony of New Brunswick, which had similar British institutions they were accustomed to.

In Quebec, the tolerant policies for Catholicism and French civil law appeared alien and unacceptable to the recent Loyalist migrants and threatened to unwind the social cohesion there. The British were forced to carve out a separate colony for them in 1791 -- Upper Canada (Ontario) -- that would have familiar British laws and the dominance of Protestant faith.

Lower Canada (Quebec) would retain its unique cultural and legal accommodations for French Catholics. These policies formed the basis of the protections for French language and culture throughout British rule, and later incorporated into Canada's constitution when it achieved Dominion status and nationhood in 1867.
